Hi,
(Full disclosure: I've engaged Esri Support on this issue)
Being both desperate and curious for more info on how to troubleshoot this issue, I decided to just continue with the workflow ... I checked and found there was data in the PrelimTransitions feature class (yay!) and thought to continue the workflow and fish for some more clues ...
So, following the documented workflow at the "Thin the network" step, the "Thin Indoor Pathways" geoprocessing tool (expectedly) fails with the following error:
(For your consideration: I've attached a screenshot of the gp tool run)
ERROR 180212: Unable to thin input pathways.
cannot unpack non-iterable NoneType object
Failed script (null)...
Failed to execute (ThinIndoorPathways).
(Note: Ignore the 7-hour processing time)
I'll just skip the discussion about following the guidance for ERROR 180212 and the solution not resolving the issue.
I checked the Pathways and Transitions feature classes and there was zero data in both, so this indeed is a catastrophic failure.
Looking at the Thin Indoor Pathways geoprocessing output messages, it indicates a few errors:
The less interesting one is:
WARNING 030116: The network was built, but with some errors. Error details are at "C:\...\AppData\Local\Temp\2\ArcGISProTemp3404\BuildErrors.txt".
Inside "BuildErrors.txt" were 5 entries indicating zero-length geometry in the PrelimPathways feature class.
(See, not interesting at all!)
But this one is a little more interesting:
Creating points for transition features.
The row contains a bad value. [LEVEL_ID]
Uhh, thanks?
(Hey @JunruChen: kindly consider adding this to the list of enhancements?)
Presumably this means: "There's a row in the PrelimTransitions feature class with a 'bad LEVEL_ID'" ?
If my interpretation is correct, then what is the bad value?
Anyway, I don't think there is much more to go on here, so I'll go back to looking at the Generate Floor Transitions a bit more ...
Thanks,
Derek
