Trying to run the archydro tool 'Line Parameters from 2D line' in ArcGIS Pro and it "completes" successfully, but all of the "Slp" fields are null and the below runtime error shows up in the results.
Based on my understanding there is no background processing checkbox when using pro, so the suggested fix is not a viable option. I have been able to successfully run the ArcMap tool equivalent of "Flow Path Parameters from 2D line" whenever I run in to this issue, but if there's a solution to get this to run in Pro consistently it would save me a lot of headache. My understanding is that the tool reduces the processing extent for each line feature when it is calculating the slope. The issue only occurs when I have a line feature that is too long, therefore creating a processing extent that exceeds the maximum allowed.
I am currently in Pro version 2.8.2 and archydro version 2.8.17, but have had the same issue with previous versions. Thanks!
