Function parseError

parseError(value: unknown, fallbackMessage?: string): string
Extracts a human-readable error message from unknown thrown input.

Native Error instances and error-like objects with a string message use that message. String inputs are returned as-is. Everything else receives the fallback message.
Parameters
- value: unknown
  Thrown value or error payload: native Error, error-like object, string, or anything else.
- fallbackMessage: string = UNKNOWN_ERROR_MESSAGE
  Message returned when value has no extractable message. Defaults to UNKNOWN_ERROR_MESSAGE.
Returns string
value.message for errors and error-like objects; strings as-is; otherwise fallbackMessage.
Example
```
parseError(new Error("Boom")); // "Boom"
parseError("Something went wrong"); // "Something went wrong"
parseError({ message: "from object" }); // "from object"
parseError(null); // "An unknown error occurred."
parseError({ message: 123 }); // "An unknown error occurred."
parseError(null, "Custom fallback"); // "Custom fallback"
```
