Cannot read property 'toLowerCase' of null

SaraEL_MALKI · ‎05-19-2017

Hi guys,

I am facing the error "Cannot read property to lower case of null" each time I reload the page and it solves when I refresh it, sometimes it takes several attempts to load the map and everything related to the arcgis API, ( the error is in the image below) ,I've heard it's because of the order of the libraries, that's why I am printing here my libraries.

Also I have an error that says "Multiple define' at the top of the console and as I know it's because of using both Dojo and jquery, (that error does not prevent the app from working) here is the order of my files:

<script

src="js/jquery-2.2.4.js"

integrity="sha256-iT6Q9iMJYuQiMWNd9lDyBUStIq/8PuOW33aOqmvFpqI="

crossorigin="anonymous"></script>

and those are my librairies :How can I get rid of that error definitely ?

$( document ).ready(function() {

var map,updateFeature;

require([

"esri/config","esri/map",

"esri/toolbars/navigation",

"esri/graphic",

"esri/tasks/RelationshipQuery",

"esri/SnappingManager",

I've solved that error changing the order of the files in order to call the JavaScript files first then the Arcgis API file like that :

<script

src="js/jquery-2.2.4.js"

integrity="sha256-iT6Q9iMJYuQiMWNd9lDyBUStIq/8PuOW33aOqmvFpqI="
