How to use the @parcel/diagnostic.anyToDiagnostic function in @parcel/diagnostic

error(input: Diagnostifiable, realOrigin?: string): void {
    // $FlowFixMe origin is undefined on PluginInputDiagnostic
    let diagnostic = anyToDiagnostic(input);
    if (typeof realOrigin === 'string') {
      diagnostic = Array.isArray(diagnostic)
        ? diagnostic.map(d => {
            return {...d, origin: realOrigin};
          })
        : {
            ...diagnostic,
            origin: realOrigin,
          };
    }

      type: 'log',
      level: 'error',
      diagnostics: Array.isArray(diagnostic) ? diagnostic : [diagnostic],
    });
