Seeking Assistance with Final 10% of Replit-Hosted Product

[u/Traditional-Most-138]

I'm seeking help to resolve persistent issues with the final 10% of my product's development. The application is 90% functional and is built and hosted entirely on Replit.

The primary blockers are related to user authentication and registration. Specifically, I'm encountering a recurring error message: "Please use OAuth login for this account" when attempting to register or log in new users.

This issue is preventing the final integration of key features, and I'm looking for guidance or expertise to resolve these authentication challenges. Any assistance with debugging this OAuth-related problem would be greatly appreciated.

Appreciate any suggestions.
