missing test cases?

POST doesn't work either.

How to replicate:

• Use the MySQL configuration

• Create a route:

  curl -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X POST -d '{                                          
     "methods": ["GET"],
     "uris": ["/get"],
     "upstream": {
     "nodes": {
        "httpbin.org:80": 1
      }
    }
  }' http://localhost:9180/apisix/admin/routes
  

• Test the route: curl localhost:9080/get

Result: {"error_msg":"404 Route Not Found"}

Also, getting all routes returns {"header":{"revision":"1689689596"},"message":"Key not found"}

Should I open new issues?
