ERROR com.appiancorp.expr.server.reaction.smartservicebridge.SmartServiceBridgeReaction - Exception occurred during activation of ReactionFunction {key='sys.smartService.start-process-2', class='com.appiancorp.expr.server.reaction.smartservicebridge.PluginSmartServiceBridgeReaction'}
...
Caused by: com.appiancorp.suiteapi.process.exceptions.InvalidProcessException: Does not exist: Process

Cause

The process instance has been archived or deleted.

Action

  • If the process has been archived and its data is needed by the parent process, follow the steps outlined in KB-1186 to unarchive the process instance.
  • Adjust archival/deletion thresholds in the Data Mangement tab to allow future process instances to be maintained for the desired amount of time after completion.

Note: Increasing the length of time process instances are maintained before archival/deletion can increase system memory and disk resource utilization of the Appian environment.

Affected Versions

This article applies to all versions of Appian.
