Hi, we have errors bring captured by RootCause pointing to RootCause JS - see the stack trace below and attached.

Any idea what is wrong or how to get rid of this issue?

This is for an Ext JS app? What version? Modern or Classic?

[mariusz.pala]

Ext JS 6.6 classic

Any pattern you recognize? Are you able to reproduce it yourself?

[mariusz.pala]

I see 3 errors in our RootCause account and users reporting that error appearing in dev console but I am not able to reproduce it.

Maybe you can enable video recording for one of your users who can reproduce it?

[mariusz.pala]

We have video recordings recorded by RootCause but I can't see anything in there, tried reproducing, but still nothing. Looks like it's only printed to the console

Ok, sounds like it'll be hard to fix. We've never seen it ourselves and we have pretty extensive coverage of RC as it's enabled on all our Ext JS based demos. If you can reproduce it, we should setup a quick screenshare to get it fixed.
