Hello everybody,  
inside consul-template I’m using service as such

```auto
{{ service "dc_cvt.patroni-cluster-a|any" }}

```

and this expression returns some strange result:

```auto
[0xc000175930 0xc000175a00]

```

But this expression

```auto
{{ range service "dc_cvt.patroni-cluster-a|any" }}
{{ .Node }}
{{ end }}

```

returns list of nodes taged by dv\_cvt just fine.

Could anybody tell me what’s wrong with expression or where to look to solve this issue?
