Python Toolbox Fails - Traceback Insufficient

[ZacharyUhlmann1]

Getting an Error in an Python Toolbox I created that works on other projects.  However the Traceback doesn't provide a line in my .pyt file belying the toolbox.  How am I supposed to debug this?

thanks - Zach

If you rewrite that list comprehension expression as a standard for loop does it produce a better traceback?

Hi @DavidSolari, it appears that line 112 was pointing to a list comprehension, or generally a line in my .pyt.  I am just accustomed to a printout of the problematic line.  I actually went back and decomposed the code and debugged in the Notebook and found the issue.

That is interesting, and I imagine you are correct that no line was printed because it was within a list comprehension.  I will mark yours as the answer.

Thanks!
