What this error means
context_management: Extra inputs are not permitted is a LiteLLM failure pattern reported for developers trying to fix litellm proxy error 'context_management: extra inputs are not permitted' when using claude code with bedrock invokemodel. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.
Why this happens
Open issue on BerriAI/litellm. Root cause: LiteLLM's /v1/messages endpoint passes context_management through to Bedrock but doesn't inject the required beta header. Clear error message with specific missing header identified.
Common causes
- When using Claude Code via LiteLLM proxy with Bedrock InvokeModel, requests containing context_management (compaction) fail because LiteLLM doesn't inject the required compact-2026-01-12 beta header into the anthropic_beta array. This is a common setup for enterprise deployments.
- Open issue on BerriAI/litellm. Root cause: LiteLLM's /v1/messages endpoint passes context_management through to Bedrock but doesn't inject the required beta header. Clear error message with specific missing header identified.
Quick fixes
- Confirm the exact error signature matches
context_management: Extra inputs are not permitted. - Check the LiteLLM account, local tool state, and provider configuration involved in the failing workflow.
- Compare the failing environment with a known working setup, then change one configuration value at a time.
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.
