PDFExport fails for Angular Grid

Hello,
We are trying to export our grid data to pdf file:

toolbarClick(args: ClickEventArgs): void {
if (args.item.id === 'Grid_pdfexport') {
this.grid.pdfExport();
} else if (args.item.id === 'Grid_excelexport') {
this.grid.excelExport();
} else if (args.item.id === this.filterKey) {
this.filter.emit(args.item.id);
}
}


pdfExport is what Syncfusion provide from the grid
/**
* Export Grid data to PDF document.
* @param {pdfExportProperties} PdfExportProperties - Defines the export properties of the Grid.
* @param {isMultipleExport} isMultipleExport - Define to enable multiple export.
* @param {pdfDoc} pdfDoc - Defined the Pdf Document if multiple export is enabled.
* @param {boolean} isBlob - If 'isBlob' set to true, then it will be returned as blob data.
* @return {Promise<any>}
*
*/
pdfExport(pdfExportProperties?: PdfExportProperties, isMultipleExport?: boolean, pdfDoc?: Object, isBlob?: boolean): Promise<Object>;


we get the following error:

core.js:7187 ERROR Error: Uncaught (in promise): TypeError: Class constructor PdfDocument cannot be invoked without 'new'

I'm just wondering if this is a known issue. 

Thanks,

Minh

Hi Minh, 
 
Greetings from Syncfusion support. 
 
We have considered “Super constructor may only be called once exception is thrown when the PdfDocument is initialized” as a defect and logged a report for the same. We will include the fix in our patch release which is expected to be rolled out by mid of July 2019. Until then we appreciate your patience.  
 
Regards, 
Thavasianand S.
