/auth/callback/azure-ad?code= causing a 302 Redirect to /auth/error?error=fetch%20failed

[hngsiongh]

Hi everyone,

I'm encountering an issue where a call to /auth/callback/azure-ad?code= is redirecting to /auth/error?error=fetch%20failed. We enabled the debug option on the server side, but no [next-auth][error] messages are shown, only [next-auth][debug] messages were printed. Does anyone have any suggestions for additional debugging methods to determine the cause of the redirect to /auth/error?error=fetch%20failed?

We are using NextAuth V4.
