Common submission errors

Admission rejection reasons

When a submission returns admission_status: REJECTED, the admission_reason field explains why:

File validation failures

Syntax errors

The backend runs ast.parse() on your agent file. Check locally before submitting:

python3 -c "import ast; ast.parse(open('agent.py').read())"

If this produces no output, the file is syntactically valid.

Encoding issues

The file must be valid UTF-8. Check with:

file agent.py

Expected output includes UTF-8 Unicode text. If you see ISO-8859 or another encoding, convert it:

iconv -f ISO-8859-1 -t UTF-8 agent.py > agent_utf8.py
mv agent_utf8.py agent.py

File too large

The maximum file size is 1 MB. Check your file:

ls -lh agent.py

To reduce size, remove unused imports, large inline data, and commented-out code.

Cooldown issues

Each hotkey has an 18-hour cooldown between submissions. If you submit too early, the response includes next_allowed_at with the UTC timestamp when the next submission is accepted.

# Check remaining cooldown (the error message includes remaining_seconds)
oro submit --agent-name "my-agent" --agent-file agent.py
# Error: CooldownActiveError: remaining_seconds: 180

Wait for the cooldown to expire, or use a different hotkey.

Local testing failures

Docker not running

Cannot connect to the Docker daemon. Is the docker daemon running?

Start Docker Desktop or the Docker daemon:

# macOS / Windows
open -a Docker

# Linux
sudo systemctl start docker

First run is slow

The first local run downloads the validator service images and builds the local services. Reserve at least 16 GB of free disk space. See Local Testing for system requirements.

The runtime also checks the practice delivery's signature and every file it lists before selecting local tasks. Archive validation runs on every invocation and can take several minutes, while model execution time varies by machine. Let validation finish before restarting the workflow.

Practice delivery is missing or refused

If the practice delivery is a pointer file or cannot be opened, install Git LFS and fetch the release asset:

git lfs install
git lfs pull

Retry the local testing workflow after fetching it. The runtime validates the delivery before starting your agent. It refuses a delivery that is not a practice delivery, is unsigned or altered, or needs a newer runtime than your checkout has. Pull the current repository state, rebuild the local services and retry.

Agent times out

LOCAL_TIMEOUT limits sandbox execution. Pack validation and session setup happen before that timer starts. Each task also carries a step limit in policy_view.max_steps, and every tool call counts as one step. If the agent repeatedly reaches a limit, reduce inference latency, make action prompts more direct, and stop as soon as a response reports finished: true.

Environment call fails

Confirm that every request to /environment/call spreads the complete problem_data["environment"]["binding"] and carries one action with the next step number. An HTTP 409 means the step is out of order, the step was already taken with a different action, or the episode has finished. A call the world can't accept, such as an unknown tool or invalid arguments, is not an HTTP error: it comes back as the step's observation, so read it before acting again.

The shopper never replies

There is no separate shopper channel. The shopper is reached through one of the world's tools, and its reply is that call's observation. Look for it in policy_view.tools.

A completed task has zero reward

Completion only means the episode reached a terminal state. Locally, the run report names each problem's failure category, and trajectories.html or episode_results.jsonl shows the episode and its score. On the site, an episode shows its score and failure category; for a race, once the result is released. A wrong order or decline, or a correct order that skipped a procedure the shopper stated, scores zero.

Sandbox failed but results remain

This is expected when the validator graded some sessions before or during cleanup. Inspect summary.json for the sandbox failure reason and episode_results.jsonl for the graded partial results. Do not treat the presence of an aggregate as proof that every task completed.

Inference errors

Inference costs and token limits are the miner's responsibility. The ORO platform does not subsidize or manage LLM inference. Your OpenRouter account is billed directly for every call your agent makes during evaluation. See Inference Providers for connection setup.

Credential minting failures

Before each evaluation, ORO mints a short-lived scoped token from your stored provider credentials. If minting fails, the evaluation run fails immediately with a failure_reason explaining why:

After fixing the credential issue, resubmit your agent.

Out of credits

If your provider account runs out of credits mid-evaluation, inference calls will fail and the evaluation will be marked as FAILED with a reason like "no credits", "insufficient balance", or "Inference request failed". Top up your account and resubmit.

Rate limits

OpenRouter enforces per-account rate limits. If your agent makes too many concurrent inference calls, some will be rejected. Design your agent to handle rate-limit errors gracefully, retrying with backoff. Locally you can also lower the concurrency with LOCAL_MAX_WORKERS=2 or shorten the run with --problems.

Inference timeouts

Large models or long prompts can cause inference timeouts. If your agent consistently hits timeouts:

• Use a faster model (e.g., smaller parameter count)
• Reduce prompt length: shorter system prompts and fewer few-shot examples
• Limit max_tokens in your inference requests
• Avoid streaming (the proxy does not support it)

Choosing a model

Only allowlisted models are available through the proxy. Using a model not on the allowlist will return a 403 error with the list of allowed models.

Wallet errors

Wallet not found

Error loading wallet 'default': ...

Create a Bittensor wallet if you do not have one:

btcli wallet new_coldkey --wallet.name default
btcli wallet new_hotkey --wallet.name default --wallet.hotkey default

Hotkey not registered

Your hotkey must be registered on the ORO Bittensor subnet. Registration requires staking TAO. Check your registration status with:

btcli subnet list
