Error when Splitting a polyline at an existing vertice

[HanZheng]

I noticed that ever since I updated my ArcGIS Pro to 3.4, I sometimes run into error split my line feature.

With more try and error, I realize the error happens only when I am splitting at a vertex point.

In the past, I never had issue with splitting at an vertex. I wonder if this is by design or a bug?

Hello @HanZheng  , yes ArcGIS Pro 3.4.0 does indeed seem to show that message when using Split at a vertex. Let me check some more details of this in case it is a defect.

Hello @HanZheng  , in ArcGIS Pro 3.4.0 I can reproduce the problem, exactly as you have described, eg using a simple Line stored in a File Geodatabase. But when I try to Split a line at a vertex in the same way in ArcGIS Pro 3.3.2, it works fine. So your next step should be to open a Support case for this to be investigated as a potential bug.
