Uncaught exception in promise when when trying to use nested components

Question

I am getting this exception when trying to use nested components:

EXCEPTION: Error: Uncaught (in promise): TypeError: Cannot set property \'endSourceSpan\' o         


        

Answer 1

I did have a similar issue with a different cause :

I built a small app using angular-cli and when the html of the component is created, it has something like :

   Component works !

So what I did is that to test a little bit my component :

   Component works !

   

      {{value}}
   

But then the error showed up.

It's just because a paragraph can't contain a block element like ( div , h1, ul etc).

So many time wasted just to spot that ...

When I do

 

    Component works !

    

       {{value}}
    
 

It's working fine ;)
