Not relevant with [ngClass] directive but I was also getting the same error as
Cannot read property 'remove' of undefined at...
and I thought to be the error in my [ngClass] condition but it turned out the property I was trying to access in the condition of [ngClass] was not initialized.
Like I had this in my typescript file
element: {type: string};and In my [ngClass] I was using
[ngClass]="{'active', element.type === 'active'}"and I was getting the error
Cannot read property 'type' of undefined at...
and the solution was to fix my property to
element: {type: string} = {type: 'active'};Hope it helps somebody who is trying to match a condition of a property in [ngClass]
