### Why do we need this PR?: This PR fixes [#3078](https://github.com/browser-use/browser-use/issues/3078), where `ChatAWSBedrock `fails when using temporary AWS credentials (e.g., STS/SSO or role-chained). The root cause was that the class didn't implement `AWS_SESSION_TOKEN`, unlike `ChatAnthropicBedrock`. ### Changes: Add support for reading `AWS_SESSION_TOKEN `when initializing `ChatAWSBedrock`. Aligns behavior with `ChatAnthropicBedrock `for consistency. ### Impact: Users relying on temporary credentials (via aws sts assume-role, SSO, or chained roles) can now authenticate successfully. No breaking changes for users with permanent credentials. ### Tested: Verified with temporary credentials (`AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `AWS_SESSION_TOKEN`, `AWS_REGION`). Confirmed successful invocation of Bedrock models where it previously failed with “The security token included in the request is invalid.” <!-- This is an auto-generated description by cubic. --> --- ## Summary by cubic Fixes auth failures in ChatAWSBedrock with temporary AWS credentials by supporting AWS_SESSION_TOKEN and passing it to the Bedrock client. Users using STS/SSO/assume-role can authenticate successfully; permanent credentials continue to work. - **Bug Fixes** - Read AWS_SESSION_TOKEN from env/params and include it when creating the Bedrock client. - Updated error message and usage docs to mention AWS_SESSION_TOKEN. <!-- End of auto-generated description by cubic. -->
