Supabase silent failures: API contract broken by caller

A developer encountered a critical issue where Supabase failed to archive customer records, despite appearing successful. The problem stemmed from the `@supabase/supabase-js` library's design, which, following a Go-like convention, returns errors within a data object rather than throwing exceptions. This meant that if the calling code did not explicitly destructure and check for the `error` property, the failure would go unnoticed, leading to silent data corruption. The developer highlights this as a case of a "silent failure" where the system fails to report its errors, emphasizing the need for callers to honor the contract of checking for errors. AI
