Using expect.any(String) in object comparison in jest

Question

I have a code like below

    expect(insertedData).toEqual({
                id: expect.any(String),
                clientId: 'client1',
                ...

I expect id should match any string, but what I get as result is

Not sure what I missed.

Also I used like below still same error

expect(insertedData).toEqual(expect.objectContaining({

Answer 1

It happens to me. Turns out the problem is not with the fields with expect.any() but the other field. Seems it just bad diff there.
