Hi All, If I have a custom Controller built for a specific use case, could I use the controller in InvokeScriptedProcessor?
I created a custom controller, deployed both api-nar and bundle-nar files, restarted nifi and created controller successfully. Also I see necessary api.jar and bundle.jar files in bundled-dependencies folder of the unpacked nar files in work directory. When I try to import my Service in InvokeScripted processor I get the below error. I assumed the dependencies should be available immediately to NiFi upon nar deployment and restart but looks like they were not available to my processor. Script1.groovy: 27: unable to resolve class com.test.controller.kudu.KuduService My controller however got properly created: [cid:77dc2233-3b8f-4347-ac25-5418b24f97c6] To solve the issue of my Service Class not being available, I found the unpacked jar file and added the dependent jar file (file containing com/test/controller/kudu/KuduService) to the ISPs module directory. This makes NiFi's UI crash, except for home page. Please see the screenshots below and error from nifi-user.log below. ISP with my jar file dependency: [cid:3f9a988f-87e9-4a94-8f55-3d30e41f644d] UI Crashed: [cid:f750709b-fe24-44b6-a19b-9f69a3233f95] I would also see the below log in nifi-user.log 2019-02-19 01:58:08,909 ERROR [NiFi Web Server-21] o.a.nifi.web.api.config.ThrowableMapper An unexpected error has occurred: java.lang.NullPointerException. Returning Internal Server Error response. java.lang.NullPointerException: null Any rookie mistakes experts can see here? Thank you, Harsha Sent from Outlook<http://aka.ms/weboutlook>
