Hello, guys. I want to know why the variables defined in the configuration file below fail. The NSLOOKUP above can be parsed normally. Is there any good solution

This is the result of my test. Both of the following should be available

{{- range service (printf (env "NOMAD_JOB_NAME")) }}{{ .Address }}:{{ .Port }}{{ end }}
{{- range service (env "NOMAD_JOB_NAME") }}{{ .Address }}:{{ .Port }}{{ end }}
