Class Method Details

.compute(error_class, message, stacktrace) ⇒ String

Computes a stable fingerprint for an error. Normalizes the message (replaces UUIDs and large integers) and uses the error class + normalized message + first stack frame.

Parameters:

  • error_class (String)
  • message (String)
  • stacktrace (Array<String>)

Returns:

  • (String) —

    SHA256 hex digest
