MqttPublish doesn't seem to work with variables

Thank you. it eas the second one. resolved.

I'm finding that MqttPublish doesn't seem to work when you use a variable for the data.  Here is an example that looks like it works from the logs but nothing gets published to the topic in Mqtt:

Macro|
SetVariable|test_bjv~atv!
MqttPublish|theater/source~{{test_bjv}}!

But just calling MqttPublish like this does work:

Macro|
MqttPublish|theater/source~atv!

Here are the logs for the failure case:
12/03/2024 00:21:23.21 · DEBUG · Server.doCommand - {{server_selectedmacro}} from dashboard-fx-l367
12/03/2024 00:21:23.21 · DEBUG · Server.doCommand - macro.test

Wow, great find! You are indeed correct! This issue is resolved in the next myServer update.

publishing works great with variables. I am having an issue with subscribing,  When I try to subscribe to anything  I get client session is unknown.
