Error with Mx9.20

[NicolasBRUNAUD]

I think i already saw this pb back in november with 9.18 or 9.19.
However i'm using 9.20 today.

The error is below. It affect the display of the whole page. a Popup containing the widget will simply fails to open.

I get the same issue with a slightly different error in the browser console: Error while applying context TypeError: str.slice is not a function

The user gets an infinite loading bar and the pop up containing the QR code never opens.

Dear Developer(s),
Any chance you update the widget for 9.20+ or even 10.0+?
It would be sad if there is no Mendix Widget which can generate QR codes on client/browser side (which is needed for offline apps).
Alternatively I will try this new widget: https://marketplace.mendix.com/link/component/207752
But I would prefer one from Mendix.
