Ionic Angular Multi App(mono repo) with Capacitor

Hi,

I’m trying to build app using angular with ionic and capacitor
I followed below wiki:

After create multiple web app. I’m not able to run command
ionic build --project=app
it throws below error:
Error: ENOENT: no such file or directory, open
“…workspace\projects\app\package.json”

Also, I’m not able to configure capacitor with multi app setup.

Please advise.

Thanks,
