RHPAM dashboard error when creating a pie chart with slaCompliance

Issue

When I create a page, after selecting a Pie rendering with a dataset (getAllProcesses), a category (slaCompliance), a series (processInstanceId) and a aggregate function (count), I have got the following message on the right side of the form ERROR :com.google.gwt.core.client.JavaScriptException: (TypeError) : a.Ku is not a function

Dataset details:

Server configuration: default-kieserver
Query target: PROCESS
Query: select * from PROCESSINSTANCELOG
