Protractor stale element reference when using the each() method

Question

I am getting the error below as a result of using the each() method in protractor. It has worked fine in the past but is now consistently failing with this error.

Answer 1

In a nutshell, it happens because each() just fires commands simultaneously against all elements. In your case you probably need to go this way element.all(bars).getCssValue('width')).then(array => {/*do what you want with returned array here*/})

* Edited *

What you want to do is

element.all(bars).getCssValue('width')).then(array => {
    // tests is at least one element will not be "0px"
    let elementHasWidth = array.some(elem => elem !== "0px");
    expect(elementHasWidth).toBe(true);
})
