Before you change production

This page includes public source URLs in the imported troubleshooting record. Compare those references with your version and environment before applying changes.

Reproduce the smallest failing action and save non-secret logs before changing configuration.
Check versions for OpenAI API, related SDKs, package managers, CI runners, and hosting providers.
Change one setting or dependency at a time, then rerun the same failing command or request.
Avoid destructive commands, credential rotation, billing changes, or security relaxations without a rollback plan.

What this error means

Background responses failures lack a stable code/name that maps to an exception class; HTTP 200 OK returned with status="failed" but no typed exception raised is a OpenAI API failure pattern reported for developers trying to fix unreliable background-mode response polling where failed runs return opaque error.code strings instead of mapped sdk exceptions (ratelimiterror, internalservererror, etc.), preventing deterministic retry logic. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

GitHub issue #3212 on openai/openai-python: The Responses API in background mode (background=True) returns HTTP 200 with free-form error.code (e.g., rate_limit_exceeded) that does not correspond 1:1 to SDK exception classes, making isinstance(e, RateLimitError) checks fail. Synchronous calls get clean HTTP-status-to-exception mapping; background polls do not. Directly impacts production retry/backoff logic for paid API consumers.

Common causes

Synchronous calls get clean HTTP-status-to-exception mapping; background polls do not. Directly impacts production retry/backoff logic for paid API consumers.

Quick fixes

Confirm the exact error signature matches Background responses failures lack a stable code/name that maps to an exception class; HTTP 200 OK returned with status="failed" but no typed exception raised.
Check the OpenAI API account, local tool state, and provider configuration involved in the failing workflow.
Reduce request pressure, check quota or plan limits, and retry with backoff instead of immediate repeated requests.

Platform/tool-specific checks

Verify the command, editor, extension, or API client that produced the error.
Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
Avoid deleting credentials, local model data, or project settings until the failing scope is clear.

Step-by-step troubleshooting

Capture the exact error message and the command, editor action, or request that triggered it.
Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
Review the source evidence below and compare it with your environment.
Apply one change at a time and rerun the smallest failing action.
Keep the working fix documented for the team or deployment environment.

How to prevent it

Keep provider/tool configuration documented.
Record non-secret diagnostics such as tool version, provider name, model name, and command path.
Add a lightweight check before CI or production workflows depend on the tool.

FAQ

What does Background responses failures lack a stable code/name that maps to an exception class; HTTP 200 OK returned with status="failed" but no typed exception raised mean in OpenAI API?

Background responses failures lack a stable code/name that maps to an exception class; HTTP 200 OK returned with status="failed" but no typed exception raised indicates the workflow described by "OpenAI Responses API Background Mode Fails Without Stable Error Code/Exception Mapping" failed in a OpenAI API context.

Is the Background responses failures lack a stable code/name that maps to an exception class; HTTP 200 OK returned with status="failed" but no typed exception raised guidance source-backed?

The "OpenAI Responses API Background Mode Fails Without Stable Error Code/Exception Mapping" page is labeled source-backed. It has 1 public source URL from github.com, so use that evidence status when deciding how much additional verification you need.

When should I avoid the quick fix for Background responses failures lack a stable code/name that maps to an exception class; HTTP 200 OK returned with status="failed" but no typed exception raised?

For "OpenAI Responses API Background Mode Fails Without Stable Error Code/Exception Mapping", avoid applying "Reduce request pressure, check quota or plan limits, and retry with backoff instead of immediate repeated requests." when the error text differs, the affected version or provider is different, or the change would touch credentials, billing, DNS, production deploy settings, or irreversible data.

What should I collect before debugging Background responses failures lack a stable code/name that maps to an exception class; HTTP 200 OK returned with status="failed" but no typed exception raised?

For "OpenAI Responses API Background Mode Fails Without Stable Error Code/Exception Mapping", collect the failing OpenAI API command or request, non-secret configuration, versions, timestamps, request IDs when available, and the smallest reproduction that still triggers the signature.
