PGRST106: "The schema must be one of the following..." error when querying an exposed schema

You may encounter a PGRST106 error, stating {"code":"PGRST106","message":"The schema must be one of the following: public"}, when attempting to query a schema via the PostgREST API that you've recently exposed.

Why This Happens: This error occurs because the authenticator role's pgrst.db_schemas setting does not include the desired schema. This creates a conflict, as PostgREST relies on this setting to know which schemas it should expose.

How to Resolve This: To fix this, you need to update the pgrst.db_schemas setting for the authenticator role. Connect to your database and execute one of the following SQL commands:

• To explicitly add your schema: If you want to add your specific schema (e.g., your_schema_name) alongside existing schemas (like public), use the following command. Remember to replace your_schema_name with your actual schema name and include all other necessary schemas already defined. ALTER ROLE authenticator SET pgrst.db_schemas = 'public, your_schema_name';

• To reset to dashboard configuration: Alternatively, you can reset this setting to allow the Supabase dashboard's configuration to take effect automatically. ALTER ROLE authenticator RESET pgrst.db_schemas;
