I have written an attribute rule in Arcade for a feature layer in ArcGIS Pro. The script validates. However, when I attempt to save the attribute rule, I encounter an error message and the rule fails to save. The error message I receive is as follows: error 999999 something unexpected cause the tool to fail when saving attribute rule.
This script gets the endpoint of the current line featureclass, then determines which point feature layers is connected to the end of the line. Then it grabs a value of the connected point feature and calcs it to the line feature.
I'm reaching out to the community for any insights, advice, or troubleshooting tips to help resolve this issue. If anyone has encountered a similar problem or has suggestions for troubleshooting steps, I'd greatly appreciate your input.
Thanks a lot for your help!
