@eraizi Hello there! I'm here to help you with bug fixes, answer questions, and guide you on becoming a contributor. Let's tackle this issue together!

The KeyError: 'position' indicates that the code is trying to access the 'position' key in a dictionary, but it doesn't exist. This error occurs in the _get_simple_metadata method within the base_app_generate_response_converter.py file.

To resolve this issue, you should ensure that the 'position' key is present in the resource dictionary before accessing it. You can add a check to see if the key exists or use the get method to provide a default value if the key is missing.

Here's a possible modification:

"position": resource.get("position", default_value)

Replace default_value with an appropriate default if the 'position' key is not always guaranteed to be present. This will prevent the KeyError from occurring.
