Unable to delete agentcore gateway openapi target

Question

Posting this bug here since I am unable to create a technical support case through the aws console.

When deleting an agentcore gateway openapi target (manually in the console or terraform) it constantly fails.

I see this error in Cloudtrail and when destroying the target with terraform
```
Error: deleting Bedrock AgentCore Gateway Target

ID: 
Cause: While waiting, unexpected state 'FAILED', wanted target ''. last error: Failed to delete search embeddings for target: 1 validation error detected. Value with
length 551 at '/keys' failed to satisfy constraint: Member must have length between 1 and 500, inclusive (Service: S3Vectors, Status Code: 400, Request ID:
) (SDK Attempt Count: 1)"
```

The error originates from a validation failure within the Bedrock AgentCore Gateway S3Vectors service. During the deletion process, the system attempts to remove search embeddings that contain a key string exceeding the permitted length of 500 characters. As a result, the operation cannot be completed successfully, and the target deletion terminates with the status FAILED.

Would be great to have someone from AWS agentcore technical team to look at this issue. I have two unused gateways in my account now because they cannot be deleted.

Thanks for the reply!

And yes, that's correct. The problem is that there is nothing I can do to delete the gateway and this requires submitting a bug report to AWS which is not offered in the AWS Support console.
