Too many values to unpack (resp_text.split)

[lbux]

Describe the bug
Sometimes, the evaluator returns null for score/explanation and sometimes it crashes with the following error:

2024-03-10 22:38:54.697 | INFO     | uptrain.framework.evalllm:evaluate:100 - Sending evaluation request for rows 0 to <50 to the Uptrain

To Reproduce
Steps to reproduce the behavior:

1. Use Factual Accuracy as a metric
2. Pass in several questions/context/responses
3. Provide valid OpenAI api key
4. Wait for results (for null values) or crash

Expected behavior
There should be no null results with valid data and the evaluator should not crash when splitting.

Additional context

I am using UpTrain through Haystack, but the issue seems to be on UpTrains side?
