Does anyone was able to fix this error? I can't run my script right now..

I got this error soon after I upgraded to Nodejs 14. No way to fix it. I had to give up with forever.

I have a same issue. I upgraded to Node.js 16.

I encountered this issue and after some experimentation I realised the project was using a very old version of forever (1.0.0) and using Nodejs 18. Once I updated forever to the latest 4.0.3 I no longer saw the issue.
