KB-1181 "The External System [identifier=ahc.collection] does not exist, has been deleted, or you do not have sufficient privileges to access its data" error thrown when running an Appian Health Check

Symptoms

Appian Health Check’s data collection fails to execute and throws the following error in the application-server.log:

[Appian Work Item - XXXXXX - ProcessExecXX : UnattendedJavaActivityRequest] ERROR com.appian.integration.httpclient.function.HttpFunction - ConnectorRuntimeException [title=Failed to retrieve value from SCS username=, com.appian.integration.core.exception.ConnectorRuntimeException: ObjectNotFoundException[ahc.collection]: The External System [identifier=ahc.collection] does not exist, has been deleted, or you do not have sufficient privileges to access its data. (APNX-1-4217-001)]

Cause

This could happen if the Health Check application and the Health Check plug-in are on different versions. Typically, this would be seen if the plug-in is updated to the latest version, but the application is not. The code is calling an object that is not part of the application.

Action

Download both the latest version of the Health Check Application and plug-in from Forum and update your app and plug-in. If you’re on Appian Cloud, you will have to raise a support case to get the latest version of the plug-in deployed.

Affected Versions

This article applies to all versions of Appian.
