As seen on Cloud endpoint portal/ application portal

Can you show the full swagger file? Or a self-contained example that reproduces the error? — countunique, Mar 15 '21 at 20:05
hello @countunique I have edited the question to include full swagger definition and screenshot to support it. Hope this helps — Juhi Gupta, Mar 16 '21 at 11:43

According to Cloud Endpoints on Cloud Run Official Documentation, I can only see the .json MimeType is used in the example.

The Cloud Endpoint service definition should be based on OpenAPI Specification v2.0, also known as Swagger 2, which describes the surface of your backend service and any authentication requirements.

So checking the OpenAPI Specification v2.0 in GitHub, I was not able to see xml specification in the MimeType Section. However in the Swagger Official Documentation, I can see that the xml media type is supported as well.

So I would like to ask you to check all the steps provided in the Cloud Endpoint on Cloud Run Official Documentation.

In the screenshot, I can see 404 NOT_FOUND error, this error is mentioned in the Troubleshooting section of Cloud Endpoints, so please have a look into it.

GCP Cloud endpoint portal does not show xml definition defined in swagger
