I second this, had the same issue while trying to build it on Ubuntu. Changing

"engines": {
	"vscode": "^1.23.0"
},
"devDependencies": {
	"vscode": "^1.1.34"
}

to

"engines": {
	"vscode": "^1.60.0"
},
"devDependencies": {
	"vscode": "^1.1.37"
}

in client/package.json fixed it for me

Sadly it seems development of this repo is has stopped. @SyamSundarKirubakaran is the only contributor and didn't make a change in over a year. This is the most promising LSP for Processing i have seen so fare. So I'm continuing his work over at my fork. Maybe in the future he is willing to pull my fork in to this repo.

Hey @Efratror its true that my efforts towards this project has reduced and unfortunately, I can't mentor for this project for the upcoming GSoC.

But I'll make sure to sync with Processing Foundation's admins to see if there is a possibility of a transfer of ownership for this project.

If you're interested in contributing to this project. I'd recommend you to continue your contributions in your folked repo - I'll review and merge in the future (this might take sometime / can't specify when). I'll also have to spin up LSP and see if everything works as expected - deprecation happens quite often on the js world.

If you're looking to participate in GSoC. I'd recommend you look for alternatives as we have shortage of mentors for this project as of now.

Hey @SyamSundarKirubakaran, Had to lookup GSoC, nice initiative. But like i've said this is the most promising vs code extenstion i've seen. Especially with the LSP function. So that's why I was interested. Now i've read the GSoC project i had no idea you guys were updating the java mode classes to a more universal server type.

At the moment i've added windows and multiple "tab" support over at my fork. Sadley i've closed and deleted the branches i had created. Because i've mad the false assumption you've ceased development. Do you know a way to reopen these or make new branches with old commits? Then i can send you the pr's. Since i'm also interested in the extension for vs code do you mind if i send pr's for the client that as well?
