Feature info widget only display for the first selection

[BrandonGuo]

I have a web map, its pop-up window contains a customised expression using the arcade buffer function to find the nearest address.

In the map viewer, the pop-up works ok without error; but in Experience builder, the info widget only displays for the first feature selected. Select another feature will pop an error window. After clear selection, reselect, the info widget works again. 

Any idea how to solve this issue? Thanks.
