    Class RnException<ErrObj>

    Custom exception class for Rhodonite framework errors. This class extends the standard Error class to provide enhanced error handling with structured error information from RnError objects.

    const rnError: RnError<string> = {
      message: "Operation failed",
      error: "Invalid parameter"
    };
    const exception = new RnException(rnError);
    throw exception;

      Parameters

      • err: RnError<ErrObj>

        The RnError object containing the error message and details

      Returns RnException<ErrObj>

      try {
        // some operation that throws RnException
      } catch (error) {
        if (error instanceof RnException) {
          const originalError = error.getRnError();
          console.log(originalError.message);
        }
