@ChuckJonas thanks, any chance you can share what's the content raised the decoding error? We may have a bug elsewhere.

unfortunately not really as I was in the middle of a complicated agent eval so there were many parallel requests happening.

The original error seems to have been: json.decoder.JSONDecodeError: Expecting ',' delimiter: line 1 column 12 (char 11).

This would have been a bedrock-runtime -> converse call.
