ArcGIS Enterprise Sites 10.8.1 : Attribute table does not show anymore for Feature Layers

We have an open data portal based on ArcGIS Enterprise Sites 10.8.1 (

All used to work fine, but recently I noticed that the attribute table is not been shown anymore, when I click on Data in the detail view of a dataset (see below). I am not sure when this changed exactly, but I am pretty sure that nothing on the data side changed.


Is this maybe a bug that was introduced with one of the ArcGIS Enterprise updates? When I click on one of the features I can see the information from the attribute table for this feature, which means that it is likely not a problem with access rights. In Portal for ArcGIS it still works as it should.  

Any help would be appreciated.

Hello Szu,

Thanks a lot for the tip. 

However, I have checked and the .wasm extension seems to be registered properly (see below). 

I tried removing and then re-registering (with a reboot of the server), but the result does not change.


Do not hesitate to share any other idea with me that comes to your mind.
