supertest use case with error "SyntaxError: Unexpected identifier"

[brunolnetto]

I write a boilerplate NodeJS app, and use supertest+jest as tester. After writing some tests, I starter having the issue below by command run npm run test:

SyntaxError: Unexpected identifier
    at ESMLoader.moduleStrategy (node:internal/modules/esm/translators:119:18)
    at ESMLoader.moduleProvider (node:internal/modules/esm/loader:468:14)
    at async link (node:internal/modules/esm/module_job:67:21)

It does not give me any hint where the problem is in my code. Do you understand it?
