Summary
The Bedrock tracer was causing a runtime error when customers tried to read the response body after a model invocation.
Updated the
mock read()method to accept the optional size parameter:lambda size=-1: response_bytes[:size] if size > 0 else response_bytes, making it compatible with boto3'sStreamingBody.read()signature.This ensures the traced response behaves identically to the original boto3 response for downstream code.
