Hi @xuanlv0703 – welcome to the Glitch forum! Could you share your project name (if it’s public?) This is just a shot in the dark, but when you look at the package.json in the editor, do you see any warnings for syntax errors? That’s what has caused that kind of error for me in the past.
If you’re only seeing the error sometimes (without any changes in your code) that might be because the project is running low on space, I think? If you look under Tools -> Container Status do you see anything?

I used to experience this aswell, I found out that remixing the project while it isn’t throwing that error and running pnpm install in console should fix it

hi @SpeedyCraftah i use npm, but project is working, so after sometime it’s appear above error, so it’s mean npm install had run before.

Glitch uses pnpm by default, which means you should really use pnpm instead of npm
