Mustache Templates and msg property naming convention

[xs539]

Node-RED version: 4.0.5
node-red-contrib-home-assistant-websocket version: 0.74.2

My notify Action node stopped working:

It seems it is not able to parse camelCase properties, when I change the property to all lowercase (alerttargetpush) it does in fact work again.

What is the naming convention for message properties in Mustache Templates?
The docs show only lowercase examples but it does not state anything about uppercase.

Should I avoid using uppercase characters?

This looks like a bug. The action string is converted to lowercase before any template variables are rendered.

Line 48 in 43d3e09

let action: string = parsedMessage.action.value.toLowerCase();
