KB-1448 "The artifact URI is not a valid plugin artifact" error thrown when deploying the SAP connector

Symptoms

When deploying the SAP connector the following error appears in the application server log:

Windows

ERROR com.appiancorp.plugins.LoggingPluginEventListener - Failed to load Plug-in 'sapjco3.dll' (sapjco3.dll) version 0.0: 'The artifact URI <APPIAN_HOME>/_admin/plugins/sapjco3.dll is not a valid plugin artifact'

Linux

ERROR com.appiancorp.plugins.LoggingPluginEventListener - Failed to load Plug-in 'sapjco3.so' (sapjco3.so) version 0.0: 'The artifact URI <APPIAN_HOME>/_admin/plugins/sapjco3.so is not a valid plugin artifact'

Cause

The SAP native library must be placed in the <APPIAN_HOME>/_admin/plugins directory for the SAP connector to function correctly. However, this library is not a valid plugin, and thus an error occurs when the application server tries to deploy the sapjco3.dll or sapjco3.so file.

Action

This error can safely be disregarded as long as the "Appian Integration - SAP" plugin has deployed correctly:

[Appian Plugin Hot Deploy] INFO com.appiancorp.plugins.LoggingPluginEventListener - Successfully installed Plug-in 'Appian Integration - SAP' (appian.integration.sap.function.sap) version 1.0.51.

Affected Versions

This article applies to all versions of Appian.
