This exception gives us information in the traceback about how to find what went wrong. Without that, we can't speculate as to what is going on.  There is a good answer here on working through NoReverseMatch exceptions:  https://stackoverflow.com/questions/38390177/what-is-a-noreversematch-error-and-how-do-i-fix-it
