I'm trying to see if a entry exists on an API call that returns {data:null} if the entry does not exist. When the call resolves I get the following error:
Cannot read property 'constructor' of null
What I want to do is if the entry doesn't exist I want to create it. If it does exist I want to update the model. Not sure what I'm doing wrong.
Also I created the API to fit JSON API standards so I can change the response of the server as well.
