      Hi all,
      After using my mirror for some some, I would like to add some custom features using the MMM-Buttons modules, forked / developed by @sdetweil
      After downloading and installing the module, pressing a button does not trigger the desired actions.

      Instead, some “beautiful” logs are coming after restarting my MagicMirror using pm2:

      2025-06-08 00:52:32.659] [ERROR] Whoops! There was an uncaught exception...

        syscall: 'write'
      } 
      

      I’m using the latest MagicMirror release.
      Do you have any tips, where I can have a look?

      Thanks :)

        @schlomm the bookworm os requires some configuration for the gpio pins. I think you can do this w raspi-config
        Edit: this is not correct, my mistake (Sam)

        I am not the author. I just fixed the Postinstall process

          @schlomm Did you try the fork on the module list?

            @KristjanESPERANTO I set up a fresh MagicMirror instance and checked the https://github.com/MarcLandis/MMM-Buttons repository. As a result I get the same issue:

            [2025-06-09 22:57:35.709] [ERROR] Whoops! There was an uncaught exception... 
            [2025-06-09 22:57:35.718] [ERROR] Error: EINVAL: invalid argument, write

              code: 'EINVAL',
              syscall: 'write'
            }
            

            …Yesterday evening I tried to fix the issue of not beingable to control the MagicMirror using some buttons. Digged into the original module, asked help of ChatGPT, debugged some functions and as a result I have a running version for Bookworm.
            I’ll try to put this in a Github Repo - will update this thread as soon as I did :)

            @sdetweil You’ve said that I only need to change some settings in the rasp-config. Do you have any additional information what needs to be changed?
