Unable to login "Supabase is not configured. Check environment variables."

The issue is that your Supabase environment variables need to be properly configured in v0’s project settings.

  1. In your v0 chat, click the Settings gear icon (top right corner)
  2. Go to Environment Variables
  3. Check if you have these variables:
    NEXT_PUBLIC_SUPABASE_URL
    NEXT_PUBLIC_SUPABASE_ANON_KEY
    If they exist:
    • Click on each variable to edit it
    Important: Enable all three environments: Production, Preview, and Development
    • Click save and then publish your project
    If they don’t exist:
    • Go to the Integrations tab in settings
    • Make sure to enable all environments when prompted
    After making these changes, the v0 should be able to access your Supabase configuration and stop the error loop. Let me know if you need any clarification!
