Trouble calculating fields on Hosted Feature Layers in ArcGIS Pro

[ZField]

I'm wondering if anyone else has had issues using the field calculator on hosted feature layers brought into Pro from ArcGIS Online through the content portal. Whenever I try to calculate, I encounter an error (see screenshot below). However, if I import the hosted feature layer into a local geodatabase and run the field calculator on a field, it works fine.

I have full editing capabilities on the hosted feature layer, and I am the owner and author of the data. Unfortunately, I don't want to resort to saving a local copy of the data and overwriting the web layer, as this causes problems in other applications downstream.

Edit: Just to clarify, the error occurs when I use the field calculator in the hosted feature layer (GRID) with a join from a different feature layer. I have attached a screenshot of the error message, ERROR 999999.

Are you able to post a screenshot or the exact text of the error you see ?

I also had similar problem.  We did not get an error , but at the end of th calculate process, now new data was added.

I'm having this problem using Pro 3.1.4:  I join a table to a hosted feature service and all field calculates from the joined fields are empty.
