Handle Supabase query errors explicitly | BeforeMerge Rules | BeforeMerge

Why This Matters

Supabase client methods return { data, error } — they never throw. If you destructure only data, errors are silently swallowed.

Good

const { data, error } = await supabase
  .from("rules")
  .select("*")
 
if (error) {
  log.error({ error }, "Failed to fetch rules")
  throw new Error(`Failed to fetch rules: ${error.message}`)
}
 
return data

Bad

const { data } = await supabase.from("rules").select("*")
return data  // could be null if query failed!
