Common questions
Error explainer, explained
How matching works and what it does not cover.
Does this send my error text anywhere?
No. Matching happens entirely in your browser against a fixed list of known error codes. Nothing is sent to a server.
What if my error is not recognized?
The tool shows any error-code-shaped text it finds and points you to the full error library to search manually.
Does this cover Flow and Apex runtime errors too?
The library focuses on deployment and DML errors, the kind that block a release. Runtime debug logs are out of scope.
How often is the error library updated?
New entries are added as they show up across real Salesforce DevOps teams. Browse the full library any time.
