Python Toolbox Broken after Upgrade to Pro 3.2

ZacharyUhlmann1

Displaying the broken path symbol (see screenshot). Right Click --> Check Syntax yields "No syntax errors". These were toolboxes that functioned fine from 2.9 thru 3.0.2, and then broke upon upgrading to 3.2. I continued to 3.3 and 3.4, but still broken. There are a couple toolboxes that did NOT break. I can't determine why they survived and the others didn't.

Are you able to cut one of these toolboxes down to a minimum reproduction of the error and then post it here?

Hi David. I think it's more efficient to include the entire .pyt as the they are 180 lines and 100 lines respectively. I can share a GitHub repo with an example of a functioning Python Toolbox and one that doesn't? For my part, I manually tried reconciling differences between the two and ruled out culprits. For instance:

modules and packages imported
This header:
- # -*- coding: utf-8 -*-
Verified that the Python Toolbox datatypes were not deprecated in 3.4 i.e. "Layer", "DEFolder","GPString", etc.
the updateParameters method with either version (with or without code blocks in the method):

# Version 1
def updateParameters(self, parameters):
        return parameters
# Version 2
def updateParameters(self, parameters):
        return

Happy to share the repo. I could drop 300 lines of python in a response if not.

thanks,

Zach

A Github repo is great, please post it when you can.

Does NOT function

does Function

Possibly related to the updateParameters method since my two functioning examples (only one shared) have no code block or functionality in that method.

Thanks David
