Module.arguments is undefined

[キャロウ マーク]

I have a —pre-js file that contains only

Module.arguments: [ '--load-gl’ ];

I am generating HTML. When I run my app after adding this to the build I get

Module.arguments is undefined

What am I doing wrong?

I also tried

Module[‘arguments’].push(‘—load-gl’);

and got the same exception.
