Unable to start RHPAM due to jbpmHumanTasksWithVariables query timeout

Solution In Progress - Updated -

Issue

After working with RHPAM 7.0 for some time, we have around 20.000 tasks created. During the server startup, the query service to fetch task variables is throwing the below error:

ERROR [org.dashbuilder.exception.ExceptionManager] (default task-15) Can't lookup on specified data set: jbpmHumanTasksWithVariables: org.dashbuilder.dataset.exception.DataSetLookupException: Can't lookup on specified data set: jbpmHumanTasksWithVariables

Caused by: org.kie.server.common.rest.NoEndpointFoundException: No available endpoints found

It seems this query is trying to fetch all data from the database, and due to the high record count, it is not responding within SLA and request times out.
