Hi there,
I tried to write some data to a ArcGIS Portal feature service using the new writer. It skipped my feature as globalid was NULL, missing or empty:

So i fell back to the old writer and this writes features fine. It sees that globalids are read-only and ignores them, along with the other ArcGIS server managed fields:

I imported the same layer from the feature service using the writer - import layer approach, and fed the same data into both of them in the same workspace. One works, one doesn’t.
Am I missing something?
Thanks,
Marc
