Supabase module broken — [406] The schema must be one of the following: public, graphql_public
Started today (May 19, 2026). All existing Supabase scenarios are still running fine, but I cannot configure any new Supabase modules — the Table dropdown fails to load with the above error.
This appears to be related to Supabase’s breaking change announced here:
Specifically, Supabase disabled pg_graphql by default on May 18, 2026. The Make.com Supabase connector appears to use GraphQL to introspect the schema and list available tables.
I have already tried:
Refreshing the connection
Creating a brand new Supabase connection with a fresh API key
Enabling pg_graphql via the Supabase Dashboard → Integrations → GraphQL (shows as INSTALLED)
Running NOTIFY pgrst, 'reload config'; in the SQL editor
Running ALTER ROLE authenticator SET pgrst.db_schemas TO 'public, graphql_public'; NOTIFY pgrst, 'reload config';
None of the above resolved the issue. Has anyone found a working fix? Is Make aware of this and working on a connector update?
I’m not at all technical, but just noticed this;
pg_graphql is installed in the graphql schema (Supabase requires this, it cannot be changed). However the error message references graphql_public. This suggests Make’s connector may be hardcoded to look for graphql_public specifically, which may never have existed or may have been a legacy schema name?
Yes, I am encountering the exact same issue. It started yesterday, May 18, 2026.
I tried deleting and recreating the connection, but the error remains. I also tried creating completely new Supabase tables, but the issue persists. Therefore, I am quite confident that the problem lies with Make’s system rather than Supabase.
As a temporary workaround, I have been using Gemini/ChatGPT to generate the module’s JSON Blueprint and importing the entire JSON block directly into Make.
By doing this, the Supabase modules can be executed successfully. However, configuring them normally through the Make UI remains completely broken as of today, May 19, 2026.
