Class extends value undefined

[Athoh]

Hello,

I am getting error

TypeError: Class extends value undefined is not a constructor or null

      at Object.<anonymous> (../node_modules/supertest/lib/test.js:15:20)
      at Object.<anonymous> (../node_modules/supertest/index.js:14:14)

When trying to run supertest on my app. through jest --silent supertest version -> 6.3.1

Test code

import supertest from 'supertest';
import app from './app';

describe('App', () => {
  it('should reach /', () =>
    supertest(app)
      .get('/')
      .expect('Content-Type', /json/)
      .expect(200));
});

jest config:

"jest": {
    "setupFilesAfterEnv": [
      "<rootDir>/../jest.setup.ts"
    ],
    "moduleNameMapper": {
      "^@airbus/lib-transfo-utils/(.+)$": "@airbus/lib-transfo-utils/dist/$1/index.js"

        "lines": 90,
        "statements": 90,
        "functions": 90
      },
      "**/*.ts": {
        "branches": 50,
        "lines": 50,
        "statements": 50,
        "functions": 80
      }
    }
  }

Do anyone as any idea on root cause and how to fix ?
