Hi @navprabhat1049,

Given what you have mentioned above, the **404 not found** error occurs due to the missing `api/auth/[auth0]/route.ts` file from your project. After initializing it, you should be able to call any [SDK mounted routes](https://github.com/auth0/nextjs-auth0/tree/main?tab=readme-ov-file#getting-started).

You can follow the steps mentioned in here for the [V4 Migration Guide](https://github.com/auth0/nextjs-auth0/blob/main/V4_MIGRATION_GUIDE.md).

I hope this helps, and you can let me know if that fixes your issue.  
Best regards,  
Remus
