vue-jest: Jest coverage reports cause an error with v4.0.0-beta.2

I just decided to give the latest beta a spin, and it worked well for running the unit tests, but when also trying to add a coverage report, I got:

resources/components/NotificationBox/NotificationBox.spec.js
  ● Test suite failed to run

    /home/daniel/Repos/omm/resources/components/NotificationBox/NotificationBox.vue: don't know how to turn this value into a node

Downgrading to v3.0.5 fixed the issue and printed out coverage reports again.

I am using:

"babel-jest": "^25.5.1",
"jest": "^25.5.3",
"nuxt": "^2.12.2",

Trying to upgrade to babel-jest@26.0.1 and jest@26.0.1 results in

I just tested and it works! I’m glad I could help with it

Hi @lmiller1990 Thanks for your work on this. I am on 4.0.0-beta.6 now, but I am still getting the same error message when trying to generate coverage reports. Does it work for you with the latest release? A sidenote: I installed it from github since I don’t think the latest beta versions are on npm yet?

Moreover, my tests now appear to fail for all .vue files when running with coverage, while these pass whenever I run jest with the --no-coverage flag.
