I've got the same problem. With production build (compressed version), uncompressed works well.

Same issue as well on 1.9.17 down to .11, haven't gone back further then that

[webdeveloper001]

I got that issue as well on 1.3.4

What build setup do you have?

[webdeveloper001]

What do you mean?

@zarincheg mentioned that

@webdeveloper001 are you using a <script src="[CDN URL]" /> tag?

[webdeveloper001]

I don't use interactjs directly. I am using react-calendar-timeline module which has interactjs as a dev dependency.

[JordanPawlett]

I'm experiencing the same issue with interactjs i'm installing it due to it being a peerDependency of react-calendar-timeline.
I can produce a successful build resolving the version to 1.3.4 in my applications root package.json.

"resolutions": { "interactjs": "1.3.4" }

Additional info to help debug the problem:
I'm using create-react-app to provide webpack config for the build/minification process.

I'd appreciate minimal a jsfiddle or codesandbox, etc. demo that reproduces this error :slightly_smiling_face:

[JonathanPicques]

For those who are using React: bumping react-scripts to ^3.4.1 and babel-loader to ^8.1.0 did the trick.
