On Install: (node:13734) MaxListenersExceededWarning: Possible EventEmitter memory leak detected.

[DamageIncorporated]

I don't know if this is a serious issue, but I saw it during installation of the module and to be safe, I post it anyway:

The following message appears multiple (10+) times in the terminal while running npm install:

(node:13734) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added to [TLSSocket]. Use emitter.setMaxListeners() to increase limit
after that, the install seems to finish okay.

Now I'll try to configure it in my new MM² smart display and see if it works ;-)

When I try to start the Magic mirror with this plugin activated, I get the following Error message in terminal:

[14206:113/14243.54730:ERROR:gbm_wrapper.cc(253)] Failed to export buffer to dma_buf: Datei oder Verzeichnis nicht gefunden(2)

This messages appears multiple (10+) times and then the start script hangs until I send a SIGKILL with ctrl-c: No mirror display appears.

I hope this helps and it's not me who makes a stupid beginner's error here, but AFAIR I did follow the MM-documentation and this readme carefully.

deactivating the plugin in config.js for now, but ready to help debugging when instructed ;-)

Hello @DamageIncorporated ,
thanks for creating this bug report!

thats a really strange error message, especially because the file name .cc within ERROR:gbm_wrapper.cc(253).

Could you provide me with more informations of your setup? I cannot reproduce that issue, so the following information would be useful:

• What device are you running the MM on?
  • e.g RespberryPi3, PI4 or ZeroW
• MagicMirror Version
• NodeJS Vesion

Thanks!

Hey, I had the same problem. It's a bit silly that with pm2 you only ever see the last 15 lines in the log. I looked at the entire log and found the following error:

I took a closer look and the only problem is that the request library is not installed. So I made an npm install request in the MagicMirror directory and immediately everything works again 👍
