Each code pairs with a stable title, a per-occurrence detail sentence, the provider’s verbatim reason, and remediation steps. Every code also states fault attribution: whether the failure came from your AWS account’s configuration, from your application’s code, from Fjall’s platform, or could not be attributed automatically.
