Configuring Agent Assist in UI builder (custom scoped application, Vancouver)

[Community Alums]

Hi All,

I'm developing a scoped application that contains a workspace created using UI builder (from scratch). On the record page's Agent Assist tab item: 

I've configured as follows:

The table configuration, looks ok to me, when I load the page the agent assist just sits at loading and is unresponsive:

I've noticed that an error is logged when the page is loaded:

java.lang.NullPointerException: java.lang.NullPointerException: com.snc.contextual_search.impl.service.SearchServiceImpl.validateQueryString(SearchServiceImpl.java:1139)
com.snc.contextual_search.impl.service.SearchServiceImpl.search(SearchServiceImpl.java:170)

l've checked this document KB Article but the record page looks different to what I see (maybe the doc screenshot refers to a legacy version of the record page?).

Does anyone have any suggestions on how to troubleshoot this issue?

Thanks,

Tim.
