Hi.
I'm working on a typescript project, and I'm using jest to run the tests.
I introduced ttypescript and ts-transform-paths but now I have a strange error: for each test I have an error with this message:
● Test suite failed to run
TypeError: Cannot read properties of undefined (reading 'impliedNodeFormat')

The error doesn't come up if I remove { "transform": "@zerollup/ts-transform-paths" } from compilerOptions.plugins
For reference this is the content of my tsconfig.json

};can you help me understanding what is going on?
