Jest - I have a nested error when more than one file

I have two test files, when I rename and comment one of them, the test will pass successfuly, otherwise will always throw this error:

 FAIL  src/features/user/auth/register.resolver.test.ts (10.045 s)
  ● Register › a new user with a valid form › call register resolver and return the registered user

    Tests cannot be nested. Test "encountered a declaration exception" cannot run because it is nested within "call register resolver and return the registered user".

And here the test files: https://gist.github.com/srgrcp/01fbbd4df391a90c25c8c60622bc2514

If I'm not wrong, the error says: "the is nested within ", but these tests are in different files.
