I found some similar issues that might be relevant to the error you're encountering:

1. ERROR: '<' not supported between instances of 'NoneType' and 'NoneType' - This issue was resolved by upgrading to version 0.10.0, which you are already using.

2. Failed to invoke tool: 'NoneType' object has no attribute 'items' - The suggested solutions for this issue include:

   • Ensuring that tool parameters are correctly formatted as a dictionary and that the timezone provided is valid.
   • Verifying and updating environment variables and configurations in your Docker setup, then restarting your Docker containers.
   • Considering using a different or smarter model, as switching to a higher quality model resolved the issue for another user.

The error message you're seeing suggests that there might be a None value where a string is expected, specifically related to the replace method. Ensure that all required parameters are provided and correctly formatted. If the issue persists, you might want to check the implementation of the retrieve method in the retrieval_service.py file to ensure that the inputs to this method are valid and correctly formatted ^[1].
