@midas If qgrid is a quasar app extension, then they have not adjusted their app.compatibleWith in app-ext/src/index.js
It should look like this to get rid of the issue:
@kwi This is “pdfjs” you will need to ask them. Unfortunately, I really don’t know much about this part (pdfjs). The app-ext just provides it, mostly for apps that don’t have the HTML 5 PDF reader built in (like Electron and Capicitor).
