Errors should guide users without exposing internal server details. Keep stack traces and secret configuration out of responses.
Evaluation approach
Separate external codes from internal diagnostics and provide a safe correlation identifier.
Application example
Explain whether retrying is appropriate without disclosing every internal security-rule detail.
Limits and considerations
Returning success for every failure harms client behavior and monitoring.
What should support retain?
A limited event identifier, version and error class provide a starting point. Let authorized staff retrieve the internal record rather than sending it all to the user.
Checks and decisions
- Define error classes
- Mask internal details
- Provide support identifiers
