AWS rejected the request at the HTTP layer because the request payload exceeds the size limit accepted by the target endpoint.
Error AtlasError Documentation and ResolutionObserved message
RequestEntityTooLargeException
Why it happens
- The HTTP request body is larger than the service or endpoint allows.
- A file, JSON payload, or encoded request is too large for the current API operation.
- The request is using a direct upload path when a multipart or alternative flow is required.
How to fix it
- Reduce the size of the request payload if possible.
- Use multipart upload or the service's recommended large-object workflow when available.
- Check the target API operation limits before retrying.
