Kong : {"message":"no Route matched with those values"}

Question

I had tried https://docs.konghq.com/gateway/latest/ and I am able to register service and router both but when I am calling the kong to redirect its giving below error.

service registered:

{
  "next": null,
  "data": [
    {
      "host": "testapp",
      "id": "722f19aa-101d-586e-8ecc-13994d576b46",

      "connect_timeout": 60000,
      "tls_verify_depth": null,
      "retries": 5
    }
  ]
}

router registered :

{
  "next": null,
  "data": [
    {
      "path_handling": "v0",
      "paths": [
        "/api/v1"
      ],

      "protocols": [
        "http",
        "https"
      ],
      "headers": null
    }
  ]
}

calling for kong on: http://localhost:8000/api/v1/

so that it can redirect to http://localhost:3003/

{"message":"no Route matched with those values"}

Regarding to strip_path I read the documentation, but it is not clear for me:

So, how strip_path attribute value is applied here?
