:bug: `analyze-run.sh` backtraces

[esnible]

Describe the bug

When I run analyze-run.sh I see a backtrace.

Steps To Reproduce

1. env OPENAI_API_KEY=${SNIBLE_LITELLM_TOKEN} OPENAI_API_BASE=https://ete-litellm.ai-models.vpc.res.ibm.com ./deploy-and-evaluate.sh --benchmark gsm8k --agent tool_calling
2. analyze-run.sh

It is failing for me with this message:
