How to set Authorization header in jest testing?

I have this testing code that it’s not returning what i want, and it’s sending me 401 Authorization error, am i doing something wrong? I’m new at testing. I already tried passing the raw authentication token, but still the same error.

This is the error:

GET /products › should return a list of products                                                  
                                                                                                  
expect(received).toBe(expected) // Object.is equality

Expected: 200
Received: 401

  23 |       .set("Authorization", `Bearer ${token}`);

     |                        ^
  25 |     expect(Array.isArray(res.body)).toBe(true);
  26 |   });
  27 | });
