ContainerCreate fails with error

I am trying to just create a simple container giving the API examples. I don't know enough about golang to troubleshoot this any further so I assume this might be a bug. I am able to list the containers correctly so at least I know talking to the API does work with GET

I inserted a Println statement in the assumed troubled code .

connection parameters

  endpoint := "unix:///var/run/docker.sock"
  defaultHeaders := map[string]string{"User-Agent": "engine-api-cli-1.0"}

  cli, err := client.NewClient(endpoint, "v1.24", nil, defaultHeaders)

Creation code

r, err := cli.ContainerCreate(context.Background(), nil, nil, nil, "container_name")
  if err != nil {
    fmt.Println("error with creating:", err)
    panic(err)
  } else {
    fmt.Println(r)
  }

Output after panic (truncated) I have tried supplying full configs but have reduced to nil parameters for testing only. The tests themselves use the same procedure

// my println statement
path: /containers/create, query: map[name:[container_name]], obj: {%!s(*container.Config=<nil>) %!s(*container.HostConfig=<nil>) %!s(*network.NetworkingConfig=<nil>)}, headers: map[]
