Your example appears to be point related, so may not apply, but I have had similar issues to this in dashboards using SDE data/views.
Turns out AGOL doesn't play well with fields that are not actually part of the feature class (Shape.STArea(), Shape.STLength()) and are added/calculated on the fly when you access them.
When I modified my view syntax to cast them to a different name, all seems to work fine:
SELECT OBJECTID, Owner, recnum, Shape.STLength() AS Length
rather than:
SELECT OBJECTID, Owner, recnum, Shape.STLength()
In fact, I had to create the views in order to overcome this rather than just using the feature class itself.
Hope this helps,
