fix: avoid calling headers() in middleware context#354
Merged
Conversation
Make the headers() call conditional in getAuthorizationUrl() to prevent "headers was called outside request scope" error when running Next.js standalone output with Bun. The headers() function from next/headers is designed for Server Components and Route Handlers, not middleware. When called from middleware context (via updateSession), redirectUri is already passed in, so we can skip the headers() call entirely. Fixes #288
