I am getting the following error message when I try to run a module I have developed. Any thoughts on what might be causing this?

Is this the full errorLog? How exactly did you launch VASSAL?

Yes, this is the full log. I am running this from within my IDE (IntelliJ) with VASSAL.Launch.Player set as the main class. This is normal for modules that I work on. Thanks for your help.

I suspect you’re not running with the --standalone flag, which is required
when you run the Player directly.

That worked! Many thanks.
