claude-code - 💡(How to fix) Fix [BUG] v2.1.96: Claude Code GitHub Action fails with AWS authentication [1 participants]

Error: Action failed with error: SDK execution error: Error: Claude Code returned an error result: Failed to authenticate. API Error: 403 Authorization header requires 'Credential' parameter. Authorization header requires 'Signature' parameter. Authorization header requires 'SignedHeaders' parameter. (Hashed with SHA-256 and encoded with Base64) Authorization=xxx Fetching issue comment xxxx

TL;DR

Downgrade to Claude Code version 2.1.92 to potentially resolve the 403 authentication error with AWS Bedrock.

Guidance

• The error message indicates a problem with the Authorization header, suggesting an issue with the authentication parameters 'Credential', 'Signature', and 'SignedHeaders'.
• Verify that the AWS Bedrock configuration is correct and that the necessary credentials are properly set.
• Try downgrading to version 2.1.92, which is reported to be the last working version, to see if the issue is resolved.
• If downgrading is not feasible, investigate the changes made in versions 2.1.93 to 2.1.96 to identify potential causes of the authentication error.

Notes

The root cause of the issue is unclear, but it appears to be related to changes made in recent versions of Claude Code. Downgrading to a previous version may be a temporary workaround, but a more permanent solution will require further investigation.

Recommendation

Apply workaround: Downgrade to version 2.1.92, as it is reported to be the last working version, and investigate the changes made in recent versions to identify the root cause of the issue.
