Additional context

The original issue is: https://github.com/cspotcode/node-source-map-support/issues/35, but it seems to be a Jest problem.

Here is the a patch that fixes it (thanks to @cspotcode )

Replace this code:

https://github.com/facebook/jest/blob/3a85065fe5604655e1337ffc1631f9999722c821/packages/jest-runner/src/runTest.ts#L213-L219

with:

  const resolved = require.resolve('source-map-support');
  runtime.requireInternalModule(resolved, resolved).install(sourcemapOptions);

Interestingly enough I had this error in CI (Ubuntu), but it worked fine locally (Windows). Added this to my .yarnrc.yml while waiting for this to get fixed:

packageExtensions:
  '@cspotcode/source-map-support@*':
    dependencies:
      source-map-support: '*'

ideally with some integration test that fails without the change. Possibly just the reproduction used in the OP
