I am trying to start a stream recording based on this example: [https://www.wowza.com/docs/stream-recording-query-examples](https://www.wowza.com/docs/stream-recording-query-examples)

The response I get when starting a stream recording is: { “message”: “The server encountered an unexpected condition which prevented it from fulfilling the request”, “success”: false, “wowzaServer”: “4.7.6”, “code”: “500” }

In the error log I see the following:

class com.wowza.wms.rest.vhosts.applications.instances.streamrecorders.StreamRecorderConfig.post : java.lang.NullPointerException|at com.wowza.wms.rest.ConfigBase.post(Unknown Source)|at com.wowza.wms.rest.ConfigBase.post(Unknown Source)|at org.restlet.resource.ServerResource.doHandle(ServerResource.java:454)|at org.restlet.resource.ServerResource.doNegotiatedHandle(ServerResource.java:683)|at org.restlet.resource.ServerResource.doConditionalHandle(ServerResource.java:357)

Any ideas?
