[JESii]

I am getting this error on roughly 35% of my tests -- just as was described in issue #145 package.json

I did the usual rm -rf node_modules, clear cache, yarn install multiple times to no effect. At one time I was getting a huge package.json diff with almost every @babel module being updated. I finally resolved the issue -- on my local machine --by going back to the previous commit, doing yarn install there, and then switching to the problem PR without doing a yarn install... makes no sense but now it seems to be working.

However, it's still failing in the CI/CD pipeline -- about 180 tests -- so still an issue. Upon inspection, many but not all of them are associated with displaying graphs

@JESii did you mock ResizeObserver as was described in that ticket?

[JESii]

Working on it...

[JESii]

@Semigradsky Yes, it did -- thanks! Closing this issue.
