API Request errors for better-auth on Cloudflare Workers
Hey! Has someone gotten
better-auth to work on cloudflare workers? I am trying to deploy a Nuxt 4 application (via NuxtHub) to cloudflare workers, deployment works, but better-auth fails on requests to API endpoints, despite it working flawlessly in development, so this must be cloudflare-specific issue. I consistently get:
CLIENT ERROR: POST https://app.netzo.dev/api/auth/sign-up/email 500 (Internal Server Error)
SERVER ERROR: SERVER_ERROR: TypeError: Cannot read properties of undefined (reading 'includes')
I am using better-auth-nuxt, I feel this might be related to missing ENV VARS in production, can anyone share any insight? I've tried everything which comes to mind already to no avail.
I am setting DATABASE_URL to Supabase's direct connection string, which worked previously when deploying to Cloudflare Pages, but same deployment to Cloudflare Workers (via nuxt/nitro preset cloudflare-durable is failing despite the env variable being properly set in the cloudflare console.1 Reply
Drop this in the better-auth discord. I know for nextJS your env needs to use NEXT_PUBLIC prefixes in some cases for your production URL. It also has catch-all routes so check the samples.
