Continuously getting API Error: 400 {"error":{"message":"{"message":"context_management: Extra inputs are not permitted"}. Received Model Group=bedrock-sonnet-4.5\nAvailable Model Group Fallbacks=None","type":"None","param":"None","code":"400"}}

Error Messages/Logs

TL;DR

The issue is likely due to an incompatible input being passed to the API, causing a 400 error with an "Extra inputs are not permitted" message, and a workaround may involve reviewing and adjusting the input parameters.

Guidance

• Review the API request being made to ensure that only permitted inputs are being passed, as the error message suggests that extra inputs are not allowed.
• Check the API documentation for the correct input parameters and formats to verify that the request is properly formatted.
• Consider testing the API request with a minimal set of inputs to isolate the issue and identify the specific input causing the error.
• If possible, try to reproduce the issue with a different model group or fallback to see if the issue is specific to the "bedrock-sonnet-4.5" model group.

Example

No code snippet is provided as the issue does not include specific code details.

Notes

The issue may be related to a recent change in the API or the Claude Code version, as the error started occurring from today. However, without more information about the specific API request being made, it is difficult to provide a more detailed solution.

Recommendation

Apply workaround: Review and adjust the input parameters to ensure compatibility with the API, as the error message suggests that extra inputs are not permitted. This is a reasonable first step to try to resolve the issue before considering other potential solutions.
