ERROR com.appiancorp.process.analytics2.display.DrillPathTokens - Expected a numeric id when trying to create the drillpath token: null
The error is generated when a process report has a drilldown that contains an expression in its column definition which evaluates to null.
To resolve this error message, ensure the expression in the drilldown does not evaluate to null.
