Tests failing because of a 500 internal server error

So I have my tests running each morning at 3 AM aprox. I have some tests that are failing with the same error which is:

03:12:18.785 WARNING - http://servertest/user/account/login - This page includes a password or credit card input in a non-secure context. A warning has been added to the URL bar. For more information, see https://goo. 03:12:53.997 WARNING - http://servertest/user/account/login - This page includes a password or credit card input in a non-secure context. A warning has been added to the URL bar. For more information, see https://goo. 03:13:18.146 SEVERE - http://servertest/portal/messages/team/id/46/view/onldgdl7g7SrCYl93uyGVFon1yfJP6OGpRpyiJmpQUYuoXKk - [DOM] Found 2 elements with non-unique id #undefined_hint: (More info: https://goo) %o %o 03:13:25.395 SEVERE - http://servertest/portal/messages/exportForKW/ref/onldgdl7g7SrCYl93uyGVFon1yfJP6OGpRpyiJmpQUYuoXKk/ajax/1 - Failed to load resource: the server responded with a status of 500 (Internal Server Error)

I have tried to change the id's where is it filling the user name and password as I can see on the screenshot that the last part of the password is sometimes filled in the username filed, after the user name was already filled in.

$I->wantTo('Search for a caller, go through security, save it and add notes');

//Log in
$I->amOnPage('/user/account/login');
$I->fillField("UserLogin[username]", "");
$I->fillField("UserLogin[password]", "");
$I->click('Log In');
$I->wait(2);
$I->waitForElementVisible('#AdminMemberGrid_status', 30);

//Access the call tab
$I->click('//*[@id="secondaryMenu"]/li[1]/a');
$I->waitForText('Search for caller :');```

Here the popup where I wait for text search for caller and pick up transferred call is not visible, in the screenshot it barley appears in front of the first page when I click the Call tab $I->click('//*[@id="secondaryMenu"]/li[1]/a');

I am expecting to see the text and fill the fields, adding a longer wait won't make any difference.

The other tests pass, and they have the same code.
