Describe the bug
I have been using react-calendar-timeline from the last year but I got this issue recently(from last week actually).
Until that time, it was working well. But for now, I have this issue when I try to import Components from this library.
import Timeline, {
TimelineHeaders,
SidebarHeader,
DateHeader,
CustomMarker
} from "react-calendar-timeline";

It is a problem with interact JS since version 1.9.11, I had to downgrade interactjs to 1.9.10 and then it worked. The same issue has been reported on interactjs, so hopefully that will get solved and then we can use the latest version again.

For now downgrade interactjs to 1.9.10

I am also having this error suddenly when hosting on Azure. Did you find a solution to this?

no I didn't
It's working well on dev mode but after built, it's not with this issue.
very odd

The same issue is happening with AWS deployment also, it's working fine on local but erroring out in production build. If anyone has any solution please let us know.

Versions:

"react-calendar-timeline": "^0.26.7"
"interactjs": "^1.9.13"
