Hi @Rituraj,

Welcome to the Auth0 Community!

Can you share what Auth0 SDK you are using for your app?

Thanks,

Hi @Rituraj,

I have reviewed your screenshot and noticed that the error is throwing an “Uncaught TypeError.” This happens when you try to use or access an undefined variable. In this case, it expects it to be either an object or null.

Next, it seems like you are using the jsonwebtoken library to build your auth flows.

I suggest referring to one of Auth0 quickstart SDKs to get started with a working sample app:

Let me know if you have any questions.

Thanks,
Rueben
