Asked On August 20, 2019 07:54 AM UTC

I am doing a POC for the React PDFViewer and referred https://ej2.syncfusion.com/react/demos/#/material/pdfviewer/default

After performing all the steps mentioned I get an error in the index.js of ej2-drawings which only has an export statement - "Uncaught SyntaxError: Unexpected token export"

I went to StackBlitz link in above demo but that also gives an error "Can't find package:@syncfusion/ej2-drawings".

Can you please add/update steps to use ej2-react-pdfviewer.

  • Browser: chrome
  • OS: windows 10
  • Integration version: React16
  • @syncfusion/ej2-react-pdfviewer
Please let  me know the missing info.

Thanks!

Hello Akshaya, 

Our app is upgraded to 16.7 but not all the libraries were updated along. The react-scripts version is 0.4.3. 
I think due to this the source files of Sync-fusion are not getting loaded correctly at runtime therefore issues are occurring.  I installed all the libraries mentioned under react-scripts version 3.1.1 (https://www.npmjs.com/package/react-scripts/v/3.1.1) but still it does not work.

We were doing a POC on another of SyncFusion's product and ran into a similar issue. We had a web meeting for the same and they are now able to reproduce the issue on their end, you can refer - 

Please let me know if a web meeting would help you to reproduce and fix the issue. I have attached a screenshot of the issue at my end with react-scripts 0.4.3. It would be great if there is a work around and we do not need to upgrade the libraries in order to consume SyncFusion.

Thanks!

Hi Abit, 

We can reproduce the console error with react-scripts package with 0.4.3 version and suspect this to be defect. We will analyze further on this and update you with more details on September 10th, 2019 

Regards, 
Akshaya

Hi Akshaya,

Can you please share the ETA for this fix, our one month trial period will end on 19th September but the evaluation will not be complete without the update, hence it would be difficult to decided on licensing. 

Thanks!
