Please help me regarding this error
Uncaught TypeError: Cannot read property 'model' of undefined" in Builder.js.
I'm using Extra theme from Elegant and I just updated my Wordpress to Version 4.5. When I tried to delete some sections in Divi Builder I got this error.
I don't know how to fix this. Uncaugth Error Elegant Theme

To solve the "Cannot read properties of undefined" error, use the optional chaining operator to check if the variable is not nullish before accessing it, e.g. person?. name . If the variable is undefined or null , the operator short-circuits instead of throwing an error.
JavaScript TypeError is thrown when an operand or argument passed to a function is incompatible with the type expected by that operator or function. This error occurs in Chrome Browser when you read a property or call a method on an undefined object .
The "Cannot read Property '0' of undefined" error occurs when accessing an undefined value at index 0 . To solve the error, initialize the variable to the correct data type, e.g. array or string, before accessing the index.
The "Cannot read property 'click' of null" error occurs when trying to call the click method on a null value. To solve the error, run the JS script after the DOM elements are available and make sure you only call the method on valid DOM elements.
I came across this error on the Divi Theme. This is how I got it fixed... It will probably work for you as well.

Replace these lines (2 total)
if ( view['model']['attributes']['parent'] === parent_id )
With these lines
if ( view !== undefined && view['model']['attributes']['parent'] === parent_id )
And replace these 2 functions
getNumberOf : function( element_name, module_cid ) {
var views = this.get( 'views' ),
num = 0;
_.each( views, function( view ) {
var type = view['model']['attributes']['type'];
if ( view['model']['attributes']['parent'] === module_cid && ( type === element_name || type === ( element_name + '_inner' ) ) )
num++;
} );
return num;
},
getNumberOfModules : function( module_name ) {
var views = this.get( 'views' ),
num = 0;
_.each( views, function( view ) {
if ( view['model']['attributes']['type'] === module_name )
num++;
} );
return num;
},
With these
getNumberOf : function( element_name, module_cid ) {
var views = this.get( 'views' ),
num = 0;
_.each( views, function( view ) {
if(view !== undefined){
var type = view['model']['attributes']['type'];
if ( view['model']['attributes']['parent'] === module_cid && ( type === element_name || type === ( element_name + '_inner' ) ) )
num++;
}
} );
return num;
},
getNumberOfModules : function( module_name ) {
var views = this.get( 'views' ),
num = 0;
_.each( views, function( view ) {
if(view !== undefined){
if ( view['model']['attributes']['type'] === module_name )
num++;
}
} );
return num;
},
