Deleting row after search in data explorer gives unknown error

[marijevdgeest]

How to Reproduce

When you search on a row in the data explorer and try to delete the particular row (or any rows found after search), the data explorer throws an 'Unknown Error', while the row is actually deleted. Only after refreshing the page the deleted row is gone.

Expected behavior

Deleting a row after search is deleted immediately without errors.

Observed behavior

Data explorer first shows Unknown error, after refresh the row is gone.

Note: It probably only happens after searching, but not 100% sure!

I ran into the same problem. Looks like it's a caching issue:
