Improve Error Handling for Robustness

[Prureddy]

This issue aims to enhance the code's reliability by improving error handling in critical functions, such as get_next_action_from_openai and summarize. Currently, the error handling within these functions is basic and might not cover all potential errors that could occur during execution.

Thanks for the idea @Prureddy. Could you suggest ways to improve the robustness of error handling in functions like get_next_action_from_openai? Feel free to open a PR with any improvements here!
