TypeError: Cannot read property 'name' of undefined

[hepcat72]

• Operating System: Raspbian
• Node.js version: v14.18.1
• fs-extra version::

  >sudo npm ls -g fs-extra
  /usr/local/lib
  └─┬ homebridge@1.3.5
  └── fs-extra@10.0.0

  I hope this is the right place to report this issue. I see this error in my homebridge installation (which installs fs-extras as a dependency I believe) constantly in my homebridge error log:

  TypeError: Cannot read property 'name' of undefined

  What can I do to address this?

Are you running a stock version of Node.js? That error indicates that require('fs').realpath.native is undefined on your system

[hepcat72]

This issue appears to be restricted to when you start homebridge using pm2. I have worked around the issue by switching to hb-service.

[RyanZim]

Yeah, something must be serving a non-standard version of fs there; not an issue with fs-extra.

[hepcat72]

I encountered this immediately upon updating to Node v14.18.1. I don't actually know what fs is, or fs-extra for that matter. Could it be a permissions issue?

[RyanZim]

fs is Node's native filesystem module. fs-extra is a wrapper around it that adds some additional methods; but apparently somehow we're getting a non-standard version of `fs.

[hepcat72]

I tried to check the version of fs, but I could not find it using npm ls. I just (re-?) installed it. Not sure how it could have gone missing, but I did note during my update process, there was a moment when one of the updates inadvertently removed a ton of stuff and I'd had to re-npm-install it all. So perhaps fs was removed... Not sure. I'll play around with it later and see if things work now after the fs install...

[RyanZim]

fs is a native node module, you don't need to install it; and there's no way it could be removed.

[hepcat72]

Huh. OK. Well, obviously I don't know what I'm doing, so thanks for the hand-holding. Very kind. I'll have to invest some more mental effort to figure out how this happened. I probably should start my whole pi over from scratch.

Hi @hepcat72.

I have the same issue. Did you solve yours somehow?

[hepcat72]

No, I did not, but only because I simply haven't tried to figure it out. I just worked around the issue by switching from pm2 to hb-service to manage my homebridge process, though I am also having issues with node-red running via pm2. I can start it up, but after a reboot, it doesn't run and I have to start it manually. I don't know if it's related to fs* though - and I discovered that I had 2 competing pm2 installations (root vs pi). I uninstalled the root one and crossed my fingers, but I haven't checked with a reboot since then.

But take all this with a huge grain of salt because I don't know what the hell I'm doing. I probably used sudo somewhere where I shouldn't have or something. I'm too busy with a bathroom remodel to figure it out, so I'm just treading water until I have time to set up my new pi 4.
