Error message

Member not found in organization={data.organization_id} for user_id={data.user_id}

What it means

After applying role/budget updates, the code re-reads the membership row to build the response and it comes back None — the (user_id, organization_id) membership vanished or never existed at response-building time. Raised as 404 to signal the final state could not be confirmed.
