I got exception while running tests (master branch 1a818ca) : Not enough information to infer type variable R

In ApiLevels.kt:

These tests are @Ignored. Actually, most of them fail because DataFrame.read("titanic.csv"): dataframe/core/titanic.csv (No such file or directory). And this is by design I think. They're not supposed to run, they're just there to be exported by Korro.

Yea, I know that these tests are ignored. But there is an error with compilation tests

Hmm that I cannot reproduce, the tests compile and run fine on my end :/ Maybe someone else can reproduce it?
