Resolving promises in Protactor

Question

I actually have issue with following code :

var promise = element(by.id("closeNotification")).isPresent(); // point A

console.log(promise);

promise.then((message) => {
    element(by.id("closeNotification")).click();
        browser.sleep(3000);
}, (errorMessage) => {                // Point B
    browser.refresh();
});

Here at point A, if element is present, program runs smoothly. But if element is not present, an error is thrown. At point B i have tried to handle the promise if it is rejected. Please help me with the condition if element is not present. Thanks in advance.

My issue is that element may or may not appear on every test run. Both suggested questions do not address this issue @Gunderson — Omkar, Mar 28 '18 at 14:10

move the click into if block, only when element is present, then execute click

var promise = element(by.id("closeNotification")).isPresent(); // point A

promise.then((present) => {
    if(present) { // only click when present == true
        element(by.id("closeNotification")).click();
    }
    browser.sleep(3000);
}, (errorMessage) => {                // Point B
    browser.refresh();
});

It isn't working and reason is that variable 'promise' is not a boolean type but is a promise. Hence 'if' statement does not work. – Omkar Mar 29 '18 at 05:32
