Hello,

When running a portal report using a!queryProcessAnalytics, We are seeing a below error in log file:
ERROR com.appiancorp.core.expr.a.QueryProcessAnalytics - com.appiancorp.kougar.driver.exceptions.Signal: index
java.lang.RuntimeException: com.appiancorp.kougar.driver.exceptions.Signal: index

Batch size is just 10.

Did anyone experience this issue.
