Question

Datasubset to Excel Servlet (v3.0.0) [com.appiancorp.ps.plugins.downloaddatasubsetfromrule]

Hello guys,

We just upgraded to 20.4 and found the plugin downloaddatasubsetfromrule is no longer working. We see the following error: 

      The system has encountered a problem 

      We’re sorry! A problem occurred while processing your last request.

      Please contact the system administrator for more information.

The plugin is available and loaded in the Appian. Anyone had this issue? Is there a fix for it or an alternate solution?

Appreciate a quick reply.

Thanks.

Mahesh

Hi Mahesh, I can't speak to whether it should still technically function on 20.4, but it does contain deprecated components.  We have been transitioning to the Export Data Store Entity To Excel service, which works great and also supports large data sets (no more 1 MB size limitation)!

We have a few calls to downloaddatasubsetfromrule plugin still working on 20.3 but are actively removing it due to the deprecation.

Chris, 

Appreciate your input. We checked the tomcat logs and are seeing this erro:

2021-05-07 15:29:06,295 [ajp-nio-0.0.0.0-8009-exec-2] ERROR com.appiancorp.ap2.WrapFilter - Root cause:
java.lang.NoSuchMethodError: com.appiancorp.core.expr.Expression.getAppianScriptEngineFactory()Lcom/appiancorp/core/expr/AppianScriptEngineFactory;

As stated earlier, the plugin and its functions/smart services are registered and shown Admin/Plugins page.

Sure thing - however I'm not intimately familiar with the inner workings of the plugin.  Have you tried uninstalling/reinstalling the plugin? 

Otherwise, I would recommend transitioning to the OOTB component Export DSE to Excel.
