flowise crashes on startup on my Ubuntu Linux 22.04 system.

Running npx flowise start gives me the following error:

/home/username/.npm/_npx/8b95a19c5c9c8708/node_modules/@oclif/core/lib/command.js:41
delete this.globalFlags?.json;

Can anyone tell me what's the problem and how to fix it?

Never mind. I fixed it. I had a down-revved version of node. Upgrading it fixed the problem.
