Data 360 Data Explorer error when opening Shopping Cart Engagement DMO

Hello Trailblazer Community,

I'm working on a Salesforce Data 360 POC connected to my B2B Store Salesforce org.

In Data Explorer, selecting the Shopping Cart Engagement Data Model Object produces this error:

Something's not right with the query. Check the columns or filter and try again.

• Data Space: default
• Error code: -1719234624
• Latest GackId: 11768440-431849
• WebCart Data Lake Object: records are visible.
• WebCart stream: Active; latest refresh status shows Success.
• Other Data Model Objects open successfully.
• The error persists after reducing the selected columns.

Has anyone encountered this issue, and what steps resolved it?

Thank you.
