I am trying to merge two AMP modules into one, but the content model in one of the modules seems to be not loaded since the tests are failing. So I tried to find a menu to see the deployed content models on Alfresco Web Client however there is none.
As a result I decided to use built-in
Get Class Definitions webscript to debug. You can also use this webscript to see if an expected content type exists on Alfresco or not. All you have to do is to call the webscript with your class name which in this case sc:ImageFamily for me.
Or you can call the same webscript without a class name, in this case webscript will dump every content type that exists on Alfresco.
And the response will be something similar to the following one.
