Invalid Topology [Topoengine error (2, 343).] Failed to execute (Clip).

[WendyDorman]

I'm trying to run a clip using 2 feature classes with global extents in a geodatabase in Jupyter notebook. This code has been working:

Fails with this error:

After running into this error the first time I repaired geometry using arcpy.RepairGeometry_management, but I'm getting the same error. I don't see an error 343 in the list of errors, but is this telling me where the topology error is? I suspect the error is being generated during the clip - is there any way to fix that?
