Error: "HTTP 415 Unsupported Media Type" when querying analytics events data using API

[Deepanshu.Grover]

 Getting following error while querying analytics events data using Analytics Events API:

"statusCode": 415, 
"code": "Library.Exception", 
"message": "HTTP 415 Unsupported Media Type", 
"developerMessage": "javax.ws.rs.NotSupportedException: HTTP 415 Unsupported Media Type"
...

This can happen when the content type is not used or incorrectly specified,  rerun the API query with Content-type:

Content-type: application/vnd.appd.events+text;v=2

Example Query Request

POST http://<events_service_endpoint>:9080/events/query
X-Events-API-AccountName:<global_account_name>
X-Events-API-Key:<api_key>
Content-type: application/vnd.appd.events+text;v=2
Accept: application/vnd.appd.events+json;v=2
 
SELECT * FROM county WHERE size>=30 AND population>20000

Note: Also make sure to have the right API Key as per the following doc:
