Supabase API errorSupabase: “Could not find the column in the schema cache” (PGRST204)

Rather not fix it yourself? App Fix Ticket starts with a fixed-price diagnosis, then a fixed price for the fix before any fix work.

Why the API can’t see the column, and the fix

1. 01

   The code uses a different name

   “Caused when the column specified in the columns query parameter is not found.” Supabase docs, PostgREST error codes (PGRST204)

   Postgres names are usually snake_case, while JavaScript objects use camelCase. Inserting { userId } into a table with user_id fails. Map the names before you insert or update.

   await supabase.from('orders').insert({
     user_id: user.id, // not userId
     total_cents: totalCents,
   });

2. 02

   The object has extra fields

   Spreading a whole form or API object into insert() sends fields the table doesn’t have, such as confirmPassword or id from another table. Pick only the columns you need.

3. 03

   The migration didn’t run on this project

   A column added locally or in staging doesn’t exist in production until the migration runs there. Check the column in the project your app’s URL points at, and push the migration.

4. 04

   The schema cache is stale

   “To refresh your PostgREST schema, go to your project Dashboard, and open the SQL Editor.” Supabase docs, Reload the PostgREST schema

   Less common: the API caches the database structure and may not yet see a column just added with SQL. Reload the cache from the SQL Editor.

   NOTIFY pgrst, 'reload schema';

Checked against the vendor’s docs on November 9, 2026: Supabase docs: PostgREST error codes; Supabase docs: Reload the PostgREST schema.

Rather hand it over?
