how can i launch this workflow-extension in langium 3.0.0

[zrwsmd]

i intergate langium 3.0.0 with glsp(refer to glsp workflow example) ,since langium 3.0.0 is ESM module(i used to use langium 1.1.0,which is commonjs ,vscode extension can launch well),when i press f5 and lanunch vscode extension ,an error occured,so how can i launch this workflow-extension

i have change extension module webpack.js to ESM module ,so output filename is .mjs suffix

@zrwsmd you need to bundle your code to cjs to be compatible with vscode. See also our own extension bundling code.
