E04039 — BroadcastTemplateVariableUnfillable

This template uses a variable that a broadcast has no value for. A broadcast fills in contact properties and nothing else, because that is all it knows about each recipient. Take the variable out of the template, or change it to a contact property, then send the broadcast again.

Edit the template and either remove the variable or change it to a contact property. A contact property can be one of our built-in fields, or a custom property your workspace currently has registered; publishing a version that reads an archived property is refused separately, so only a live property fixes this. Once the template is fixed, send the broadcast again.
