Try using node ^20.19.0 as it works on that version of node. However, I think I will just remove the analyzer since it's causing some hang up for users.

Thank you for your answer. My Node version was v20.15.0. I will try to update it to 20.19.0.

@danny-avila
My LibreChat is back. Thank you very much.

Also removed the analyzer in c517f66

The error persists in Node v22.0.0, tested on latest librechat-dev

[danny-avila]

Try latest node 20.x.x
