Error setting variable to form LastSubmit after turning on New analysis engine

I recently tried turning on the New analysis engine setting on my application and it then started showing errors in a formula that had previously been working fine. It seems to object to my setting of a local variable to a form's LastSubmit value in the form's OnSuccess property:

UpdateContext({ locLastRecord: frmClient.LastSubmit });
If(locFormMode = FormMode.New,
 UpdateContext({ locClientTitle: "C" & Right("000000" & locLastRecord.ID, 6) });
 Patch('Client data', locLastRecord, { Reference: locClientTitle } );
 Notify("New client record " & locClientTitle & " created", NotificationType.Success, 1000);
,
 UpdateContext({ locClientTitle: locClientData.Reference });
 Notify("Client record " & locClientTitle & " updated", NotificationType.Success, 1000);
);
... more processing

All references in the code to the locLastRecord variable return an error like: Name isn't valid. 'ID' isn't recognized:
