TL;DR

The error "Working outside of application context" suggests that the issue is related to the application context not being properly set when accessing the database.

Guidance

• The error occurs in the provider.py file when trying to access the credential attribute, which is a database query. This query is being executed outside of the Flask application context.
• To fix this, ensure that the database query is executed within the application context. This can be done by using the with app.app_context(): block when accessing the database.
• Review the code to identify where the application context is being set and ensure it is properly propagated to the point where the database query is being executed.
• Consider using a try-except block to catch the RuntimeError exception and provide a more informative error message.

Example

from flask import current_app

with current_app.app_context():
    # Execute database query here
    credential = db.session.scalar(select(ProviderCredential).where(ProviderCredential.id == self.credential_id))

Notes

The exact fix will depend on the specific code structure and how the application context is being managed. This guidance provides a general direction, but additional investigation may be required to identify the root cause.

Recommendation

Apply workaround: Ensure that all database queries are executed within the application context using the with app.app_context(): block. This will help to prevent the "Working outside of application context" error.
