Same issue here, this blog post fixed it for me: https://flaviocopes.com/cb-apply-not-a-function/

We manage to fixes this problem. we just modify the file graceful-fs.js at location node_modules\graceful-fs\graceful-fs.js

for aver environment it gives error at line 61:14 that is this line

if (typeof cb === 'function') cb.apply(this, arguments)

we just add this line in to try and catch block and its work for me

Yeah, cb is definitely a function there.

To debug this, I'll need at minimum the actual stack trace (with line number) and the output of npm ls graceful-fs (to see the version you're using). The line you're showing, in the latest released version, is definitely ensuring that cb is a function prior to calling it. So it's not that.
