They are not populated on client side. The variables get substituted in query-service.

Attached is query where environment set to dev and the payload showing this. The result is 0.
if we dont use a variable the result is good (see attached)

This kind of variable substitution doesn't work. Please add `deployment.environment` (<https://opentelemetry.io/docs/specs/semconv/resource/deployment-environment/>) to your <https://opentelemetry.io/docs/specs/otel/resource/sdk/#specifying-resource-information-via-an-environment-variable|resource attributes> and use it as full variable filter instead.
