Hello, I’m going mad here but I seem to be missing something.

I keep getting this error:

when dispatching assignBugToUser:

Here is my action creator:

And here is my reducer:

I’ve tried comparing my code to Mosh’s code but cannot find where I’m going wrong?? Also what is the best approach to debug these type of errors?

Thanks in advance for the help!

I found the problem: it seems to be happening because I put the apiCallBegan function inside curly braces in the assignBugToUser function. Is it because I was passing an object instead of a function to the action creator?  
Taking the curly braces out made it work.
