I have set our nextjs application with nextjs-auth0 SDK, I followed the documentation, and set everything as mentioned,

I keep getting “Failed to verify code verifier” when user is logged in

Please can you help fix this issue ASAP
Here the error keeps happening

I have the same issue, but only in Webkit based (Safari-like) browsers. Is this the case for you too?

Lots of problems with this SDK. I haven’t been able to get it working in months. I bet a lot of devs are finding other solutions because of it. I’m about to.

I have been able to reproduce this issue with the auth0-nextjs sample app, and created an issue on the official repo. 'invalid_grant' error upon login with Safari (WebKit) · Issue #1754 · auth0/nextjs-auth0 · GitHub
