I’m having issues connecting to my Supabase instance inside the v0 preview environment. My site works when viewed on production , but not inside v0:
I went through the native Vercel-Supabase connection process. It shows as connected/active within both the Supabase and Vercel dashboards.
If I try to add environment variables within v0, it returns errors saying they have already been added:
A variable with the name NEXT_PUBLIC_SUPABASE_URL already exists for the target production on branch undefined
A variable with the name NEXT_PUBLIC_SUPABASE_ANON_KEY already exists for the target production on branch undefined
Do I need to manually configure Supabase environment variables for the v0 editor for it to function? If so, how?

Remember, just like any other AI tool, the quality of the output that v0 generates depends on the quality of the prompt or instructions you input. So, it’s important to be clear, descripti…
And these recordings can give you a look at v0 features and strategies in action: Topics tagged v0
Finally figured it out. In case anyone is experiencing the same issue:
Open the v0 project settings.
Select each environment variable to edit.
Enable all environments: Production, Preview, Development
