Grizzly serve grafonnet missing template variables

[zabojpetr]

Grizzly Version

0.7.1

Expected Behavior

Hi,

I generate dashboard with grafonnet and I cannot see template variables in Grizzly (I run it in docer). When I generate json and insert it to grafana I can see the variables there. In grizzly I need to wrap the grafonnet dashboard with grizzly wrapper, but I expect that the output will be the same - variables will be there.

Actual Behavior

Template variables are missing in grizzly serve when I use grafonnet for dashboard generating.

Steps to Reproduce

Install packages

1. jb install github.com/grafana/grafonnet/gen/grafonnet-latest@main
2. jb install github.com/grafana/grafonnet/gen/grafonnet-v11.2.0@main
3. jb install github.com/grafana/jsonnet-libs/grizzly@master

// grr.jsonnet
local grr = import 'github.com/grafana/jsonnet-libs/grizzly/grizzly.libsonnet';
local myLib = import './online.jsonnet';

{
  folders: [],
  dashboards: [
    grr.dashboard.new('Online device - new - grafonnet', myLib)
  ]
}

// online.jsonnet
local g = import 'github.com/grafana/grafonnet/gen/grafonnet-v11.2.0/main.libsonnet';
local tdp_datasource = {
    type: "postgres",
    uid: "postgres_db_id"
};

g.dashboard.new('Online device - new - grafonnet')
+ g.dashboard.withUid("online-device-new-grafonnet")
+ g.dashboard.withTagsMixin("generated")

+ g.dashboard.withVariablesMixin(
    g.dashboard.variable.constant.new("schema", "public")
)
+ g.dashboard.withVariablesMixin(
    g.dashboard.variable.constant.new("prefix", "/")
)
+ g.dashboard.withVariablesMixin(
    g.dashboard.variable.query.new(
        "deviceid",  
        |||
            SELECT * FROM ${schema}.fancy_device_table
        |||
    )
    + g.dashboard.variable.query.generalOptions.withLabel("Device")
    + g.dashboard.variable.query.withDatasource(tdp_datasource.type, tdp_datasource.uid)
)

Then run command grr serve -w -S 'jsonnet /data/grr.jsonnet -J /data/vendor' -l debug /data

I want to try serve only the generated JSON, but when I try grr serve /data/online.json -l debug I get error
