When loading a report in /designer, users may see the following error in the application server log:
ERROR com.appiancorp.process.analytics2.display.DrillPathTokens - Expected a numeric id when trying to create the drillpath token: null
The error is generated when there is a report configured with a drilldown and the drilldown has an expression in its column definition. For those columns where the expression evaluates to null users will get this message.
The error is not necessarily an issue and can be disregarded. To avoid the message from coming up in the log, analyze the expression to avoid the result from evaluating to null for the drilldown.
This article applies to all versions of Appian.
