OpenAI integration Mealie add-on throws error

I use the Mealie add-on and tried to use the OpenAI integration to parse ingredients. Whether I use the test sentences or a real recipe, I get a message ‘Something went wrong’, and the log shows:

pydantic_core._pydantic_core.ValidationError: 1 validation error for OpenAIIngredients
JSON input should be string, bytes or bytearray [type=json_type, input_value=None, input_type=NoneType]

I have ingredients and units set up in Mealie data management. I only have one environment variable for OpenAI set up, the API key. The others are default.

Anyone has an idea what this could cause?

This sounds like an issue with Mealie or the addon, please checkout the Mealie discord (mealie.dev) for help or the issue tracker from the mealie add-on
