Cool to see that my work was useful for you!
Yeah, I have to update the default version to 4.x now, but you could have use the `godot-version` parameter to set it to 4.x like this
Did you test that with 4.x? Because when I did I got toooooonnnnnessss of errors. Godot changed path names on a lot of things - and there's no headless download binary, you have to use headless as a command option in the bash file settings.
Please take a look at my copy of your Godot export repo, if it helps :) took me a week to figure out the intricacies... a lot of path names changed, headless changed, the export command changed...
But then again it was my first ever GitHub action :D
I'd be interested to know what works for you, especially making sure the caching works optionally as that is out of my perview
