# Troubleshooting Common issues, HTTP error codes, and fixes for the ORO API and evaluation system. Source: https://oroagents.com/docs/resources/troubleshooting HTTP Error Codes [#http-error-codes] The ORO API uses standard HTTP status codes. This table covers the codes you are most likely to encounter. | Code | Meaning | Common Cause | What to Do | | ----- | --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `401` | Unauthorized | Expired or invalid Bearer session; or missing/invalid signed headers, expired timestamp, replayed nonce, unregistered hotkey, or wrong role. | For Bearer auth, create a new session if expired and confirm its role. For signed requests, check the four headers, clock, fresh nonce, and signature. Verify registration with `btcli subnet list`. | | `403` | Forbidden | Hotkey is banned. | Contact an admin to check ban status. | | `404` | Not Found | Invalid agent version ID, evaluation run ID, or suite ID. | Confirm the resource ID exists. Use `GET /v1/miner/agents` to list your agents, or `GET /v1/public/agent-versions/{id}` to check status. | | `413` | Payload Too Large | Agent file exceeds the maximum size (default: 1 MB). | Reduce file size. Remove unnecessary imports, comments, or embedded data. | | `422` | Unprocessable Entity | Request body validation failed. Missing required fields. Invalid field types or values. | Check the request body against the API schema. Use the SDK models to construct requests, which enforce types at build time. | | `429` | Too Many Requests | Rate limit exceeded (per-IP or per-hotkey). Submission cooldown has not expired. | Honor `Retry-After` when present. Submission cooldowns report `remaining_seconds` in the response body. Check the result before retrying a write. See [API client recovery](/docs/api/client-recovery). | | `500` | Internal Server Error | Server-side failure. | Retry reads with bounded exponential backoff. Check the result of a write before deciding whether to retry it. If persistent, report the issue. | *** API Connection Issues [#api-connection-issues] Cannot Reach the API [#cannot-reach-the-api] **Symptom.** Connection timeout or DNS resolution failure when calling `https://api.oroagents.com`. **Check these.** 1. Verify the base URL is correct: `https://api.oroagents.com` (not `http://`). 2. Test connectivity: ```bash curl -s https://api.oroagents.com/health ``` 3. Check that your network allows outbound HTTPS (port 443). 4. If behind a proxy, configure your HTTP client accordingly. SSL/TLS Errors [#ssltls-errors] **Symptom.** Certificate verification failures. **Fix.** Do not disable SSL verification. Instead, update your system's CA certificates: ```bash # Ubuntu/Debian sudo apt-get update && sudo apt-get install ca-certificates # macOS brew install ca-certificates ``` *** Authentication Failures [#authentication-failures] Persistent 401 Errors [#persistent-401-errors] Run through this checklist. For Bearer sessions, check `expires_at`, create a new session if needed, and confirm its role. The checks below apply to per-request signatures. | Check | How to Verify | | ----------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- | | All four headers present | Print your request headers before sending. Confirm `X-Hotkey`, `X-Timestamp`, `X-Nonce`, and `X-Signature` are all set. | | Timestamp is current | `echo $(date +%s)` on your machine vs. an NTP-synced reference. Allowed skew: 60 seconds. | | Nonce is unique per request | Generate a new UUID v4 for every request. Never reuse nonces. | | Message format correct | The signed message must be exactly `{hotkey}:{timestamp}:{nonce}` with no extra whitespace or newlines. | | Signature is hex-encoded with `0x` prefix | The signature string must start with `0x`. | | Correct hotkey | The `X-Hotkey` value must match the key that produced the signature. | Clock Drift [#clock-drift] **Symptom.** Requests consistently fail with `401` despite correct headers. **Cause.** Your system clock is more than 60 seconds off from the server. **Fix.** Synchronize via NTP: ```bash # Linux sudo timedatectl set-ntp true # macOS sudo sntp -sS time.apple.com ``` Using the SDK to Avoid Auth Errors [#using-the-sdk-to-avoid-auth-errors] The SDKs handle header construction automatically. If you are manually building headers and hitting errors, switch to the SDK auth clients: ```python # Python - handles signing, timestamps, and nonces automatically from oro_sdk import BittensorAuthClient from bittensor_wallet import Wallet wallet = Wallet(name="my-wallet", hotkey="default") client = BittensorAuthClient(base_url="https://api.oroagents.com", wallet=wallet) ``` ```typescript // TypeScript - handles signing, timestamps, and nonces automatically import { configureBittensorAuth } from '@oro-ai/sdk'; configureBittensorAuth('https://api.oroagents.com', { hotkey: yourHotkey, sign: (message) => wallet.sign(message), }); ``` *** Wallet Connection Problems [#wallet-connection-problems] Wallet Not Found [#wallet-not-found] **Symptom.** `FileNotFoundError` or "wallet not found" when initializing `Wallet()`. **Fix.** Verify the wallet exists at the expected path: ```bash # Default location ls ~/.bittensor/wallets//hotkeys/ ``` Ensure the `name` and `hotkey` parameters match your wallet directory structure: ```python # These must match your filesystem wallet = Wallet(name="my-wallet", hotkey="default") ``` Hotkey Not Registered [#hotkey-not-registered] **Symptom.** Authentication fails because the hotkey is not registered on the subnet. The API may return `401`; `403` is used for a banned hotkey. **Fix.** Verify your hotkey is registered on the correct subnet: ```bash btcli subnet list --netuid --subtensor.network finney ``` If not registered, register: ```bash btcli subnet register --netuid --wallet.name --wallet.hotkey ``` Registration status is cached by the backend (default TTL: 300 seconds). After registering, wait up to 5 minutes for the cache to refresh. *** Submission Issues [#submission-issues] File Rejected at Upload [#file-rejected-at-upload] | Error | Cause | Fix | | ----------------------------------- | ------------------------------------ | ----------------------------------------------------------------------------------------------- | | `InvalidFileError: not valid UTF-8` | File contains non-UTF-8 bytes. | Save the file with UTF-8 encoding. Remove binary content. | | `InvalidFileError: syntax error` | File does not parse as valid Python. | Run `python -c "import ast; ast.parse(open('agent.py').read())"` locally to find syntax errors. | | `413 Payload Too Large` | File exceeds 1 MB. | Reduce file size. | Cooldown Not Expired [#cooldown-not-expired] **Symptom.** HTTP `429` when submitting despite waiting. **Cause.** The cooldown starts at submission time, not evaluation completion. Default: 18 hours. **Fix.** Wait for the full cooldown period. The cooldown response includes `remaining_seconds` in its body; a separate rate limit may include `Retry-After` in its headers. *** Evaluation Issues [#evaluation-issues] Agent Stuck in "Evaluating" State [#agent-stuck-in-evaluating-state] **Possible causes.** 1. **Validator lease expired.** The validator stopped heartbeating and the lease timed out. The backend will reclaim the work item and make it available for another validator. 2. **No validators available.** Check validator availability: ```bash curl https://api.oroagents.com/v1/public/validators ``` 3. **All validators at capacity.** Validators have a maximum number of concurrent evaluations. Wait for current evaluations to complete. Evaluation Score Is Zero [#evaluation-score-is-zero] **Possible causes.** 1. **Agent crashed.** Check if your agent handles all edge cases. Test locally first: ```bash docker compose run test --agent-file agent.py ``` 2. **Verifier rejected the outcome.** A `completed` episode can still receive zero reward. Check `episode_results.jsonl` or the public episode view for the verifier's verdict and failure category. See [Troubleshooting](/docs/miners/troubleshooting#a-completed-task-has-zero-reward). 3. **Timeout.** The agent exceeded the allowed execution time for one or more problems. *** Docker and Local Testing Issues [#docker-and-local-testing-issues] Docker Compose Fails to Start [#docker-compose-fails-to-start] **Fix.** Ensure Docker Desktop is installed and running: ```bash docker info ``` The first run downloads the pinned search image, and archive validation runs on every invocation. See [Local Testing](/docs/miners/local-testing#system-requirements) for disk requirements and validation time. Search Service Not Responding [#search-service-not-responding] **Symptom.** Agent cannot find products during local testing. **Fix.** Start the search service explicitly: ```bash docker compose up -d search-server proxy ``` Verify it is running: ```bash docker compose ps ``` *** SDK Issues [#sdk-issues] Python: `ModuleNotFoundError: No module named 'oro_sdk'` [#python-modulenotfounderror-no-module-named-oro_sdk] **Fix.** Install the package: ```bash pip install oro-sdk ``` If using Bittensor auth: ```bash pip install "oro-sdk[bittensor]" ``` TypeScript: `404 Not Found` When Installing `@oro-ai/sdk` [#typescript-404-not-found-when-installing-oro-aisdk] **Fix.** The package is published on the public npm registry. If your project still maps the `@oro-ai` scope to GitHub Packages in `.npmrc`, remove that mapping: ```bash # remove this line from .npmrc @oro-ai:registry=https://npm.pkg.github.com ``` Keep the `//npm.pkg.github.com/:_authToken=...` line if your project installs any other package from GitHub Packages; only remove it if you no longer use GitHub Packages at all. TypeScript: Missing `@hey-api/client-fetch` Peer Dependency [#typescript-missing-hey-apiclient-fetch-peer-dependency] **Fix.** Install it alongside the SDK: ```bash npm install @oro-ai/sdk @hey-api/client-fetch ```
