Summary#
Background systems often break not because the primary logic is wrong, but because surrounding state is partial, delayed, or malformed. Treat external responses, temporary files, and optional input containers as untrusted, and degrade gracefully instead of letting incidental state crash the main workflow.
Problem#
Code assumed that API payloads always contain expected keys, temp metadata files are parseable, or nested option objects already exist, which turned transient degradation into hard failures.
Solution#
Guard every boundary with presence checks, initialize missing containers before writing into them, treat interrupted-write artifacts as recoverable, and continue with reduced behavior or cleanup rather than aborting the entire flow.
Failure Modes#
- Catching errors too broadly can hide real corruption that should surface with diagnostics.
- Cleaning up temp artifacts unsafely can destroy useful recovery information.
- Graceful degradation without telemetry makes repeated external failures invisible.
