问题
I started to get error, ServiceConfigException, after I've tried to add Api Management to my project just as explained here.
Commenting out ServiceManagementConfigFilter lines from web.xml lines as told here solves my problem but leaves my project without API support.
I'd love to get some help. Thanks in advance.

回答1:
Removing the ENDPOINTS_SERVICE_VERSION from appengine-web.xml magically solved the problem. Though I don't know how it is related.
Edit: Commenting out these lines solves the problem but disables api key support.
<filter>
<filter-name>endpoints-api-configuration</filter-name>
<filter-class>com.google.api.control.ServiceManagementConfigFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>endpoints-api-configuration</filter-name>
<servlet-name>EndpointsServlet</servlet-name>
</filter-mapping>
Edit: Let's add a little bit of depth why the problem occurred.
When openapi.json file deployed by using gcloud endpoints services deploy openapi.json command, it echoes a service configuration id like 2017-02-13r0. You should be using that in appengine-web.xml as the value of environment variable ENDPOINTS_SERVICE_VERSION.
Since, copying and pushing the new service name is found fairly clunky flow (and it really was), on the later stages of cloudendpoints, they changed it to, if not specified any, the latest version of ENDPOINTS_SERVICE_VERSION will be used.
