How to use the @esri/solution-common.cleanLayerId function in @esri/solution-common

// in some cases the id will not contain a layer name...it will have the dashboard id for another widget
      // in that case lookup the datasource from referenced widget
      const dashboardWidgetId: string = id.split("#")[0];
      datasourceInfos.some(di => {
        const references: string[] = di.references || [];
        const hasRef: boolean = references.indexOf(dashboardWidgetId) > -1;
        info = hasRef ? di : info;
        return hasRef;
      });
    }
  } else {
    // otherwise match the itemId and the layerId to get the correct fields and path
    const itemId: any = common.cleanLayerBasedItemId(
      common.getProp(obj, "dataSource.itemId")
    );
    const layerId: any = common.cleanLayerId(
      common.getProp(obj, "dataSource.layerId")
    );
    if (itemId) {
      datasourceInfos.some(di => {
        const matches: boolean = itemId === di.itemId && layerId === di.layerId;
        info = matches ? di : info;
        return matches;
      });
    }
  }
  return info;
}

obj.datasets.forEach((dataset: IDashboardDataset) => {
          // when the datasource has an itemId it's an external datasource
          const itemId: string = common.cleanLayerBasedItemId(
            common.getProp(dataset, "dataSource.itemId")
          );
          if (itemId) {
            const layerId: number = common.cleanLayerId(
              common.getProp(dataset, "dataSource.layerId")
            );
            datasourceInfos.some(ds => {
              if (ds.itemId === itemId && ds.layerId === layerId) {
                _updateReferences(ds, obj.id);
                return true;
              } else {
                return false;
              }
            });
          } else {
            // add placeholder for map layer datasource info so we can know the items that reference them
            // needed when item field reference are derived from another widgets datasource eg. #datasetname
            const id: any = common.getProp(dataset, "dataSource.id");
            if (id) {
              const dashboardLayerId: string = id.split("#")[1];
