I'm using a python AWS lambda function to run evaluations using Bedrock, with model Claude 3.5 sonnet and Uptrain version 0.7.1.

I'm getting an "Error when processing payload" error when trying to run evaluations, depending on the data processed.

Steps to reproduce the behavior:

Create a lambda function using python 3.11
Install uptrain
Use bedrock to run a factual accuracy evaluation
See error

uptrain.operators.language.response_quality:evaluate_local:499 - Error when processing payload at index 0: None\n
