Platform Analytics List Visualization Error: "Cannot read property 'internalType' from undefined" a

[tanvirathod]

Hi Team,

We are experiencing an issue with a Platform Analytics List visualization after upgrading to Zurich Patch 12 W34.

Error:

"Can't display this list"

"List controller data broker transform error: Cannot read property 'internalType' from undefined"

Environment:

• ServiceNow Zurich Patch 12 W34
• Platform Analytics Dashboard
• Data Source: Requested Item [sc_req_item]

What we have observed:

• The issue started after the Zurich Patch 12 W34 upgrade.
• The data source preview loads successfully and displays records.
• When editing/configuring the data source, the list displays correctly.
• The error only occurs when rendering the List visualization on the dashboard.
• I impersonated the affected user and received the same error.
• I also impersonated an admin user and received the same error.
• The sc_req_item table is accessible and returns records successfully.
• This does not appear to be an ACL, role, or data access issue because administrators experience the same behavior.
• The issue seems to occur only in the visualization rendering layer.

Has anyone encountered this specific "Cannot read property 'internalType' from undefined" error in Platform Analytics after a Zurich upgrade or patch?
