I am trying to connect Amazon Bedrock to the Cursor IDE using API credentials from my AWS account, but I keep receiving the following error:

I confirmed my AWS configuration is correct and verified via the AWS CLI that my credentials work.
It looks like Cursor might be sending an invalid Bedrock request or using an unsupported model ID.

Please help to assist. Thanks

Steps to Reproduce

  1. Open Cursor → Settings → AI Providers → AWS Bedrock
  2. Toggle Bedrock integration ON

  4. Access Key ID: (valid key from IAM)
  5. Secret Access Key: (matches IAM key)
  6. Region: us-east-2
  7. Test Model: anthropic.claude-3-sonnet-20240229-v1:0
