Permission denied error with windmill and supabase

Hi everyone, I need some help with Windmill. I'm trying to deploy it on railway using the Dockerfile and connect it to a supabase database. The deployment works fine, but I get this error when I run it and logged in:

Sql error: error returned from database: permission denied to set role "windmill_admin"

Does anyone know what's causing this and how to fix it? Thanks in advance!
