Protractor. ''No element found message'' instead of ''expectationFailOutput'' text

Using Protractor, I spotted that wished fail output is replaced by just absent element message. For instance:

await expect(await login.mainError.getText()).toBe('We do not recognize that email.', `Actual login error message: ${blabla }does not match expected: 'TEST CORRECT'`)

instead of seeing this when test failing:

ERROR: Actual login error message: ${blabla }does not match expected: 'TEST CORRECT'

I primitively see

Failed: No element found using locator: By(css selector, .common-form-error)

Do I do something expectationOutPut is not relevant? Thanks
