    @bolish Well at first I would rule out:

    MMM-Wunderlist
    MMM-remote-control
    MMM-SystemStats
    calendar_monthly
    all in default

    I have these as well and not the message you’re finding.
    What you could try out:
    There is a module MMM-Logging by @shbatm giving the logging output more detail. It’s easy to install and you don’t need to configure anything.
    That module could be able to show where the unhandled promise reection is sitting.

      OK I will give it a try this weekend and check the logs.
      Disabling them on by one (through the config.js) will not help?

        @bolish It will but it’s more work :-) That would be my next approach

            OK that didn’t help.
            MMM-Logging at least gave us the file putting the error out but not file from which it originated.

            But isn’t Linux a beautiful wild monsterous creature?
            Try this command

            find . -maxdepth 2 -exec grep -nwl  Promise 2>/dev/null {} +
            

            in the MagicMirror directory.

            “find” looks for all files in the 3rd party module directories (all files with depth of 2 directories maximum, we don’t want to have all the numerous node module files included), then it executes (“-exec”) a grep function searching the files for the “Promise” function.
            “2>/dev/null” is there to put all error output (there’s a lot) away from the standard output

            This will give you all 3rd party module files including the promise function. Then we can limit it to a few modules.

            With these you can do the “deactivate and look for errors” workflow and find out the one responsible

              this is the result I have :

              ./js/main.js
              ./js/module.js
              ./clientonly/index.js
              
              

              Seems to be linked to the core system itself only and not to any particular module?
              I’ve already made a git pull for MM itself but it’s already up to date.

                @bolish Sorry my bad. You need to do it in the modules folder. Then maxdepth 2 leads to the folder itself and all 3rd party folders.
                Sorry again!

                  !!! it’s not your fault, it’s shame on me!!!

                  Anyway, I just did it…Result is zero…Nothing…

                  pi@MagicPi:~/MagicMirror/modules $ find . -maxdepth 2 -exec grep -nwl  Promise 2>/dev/null {} +
                  pi@MagicPi:~/MagicMirror/modules $ 
                  
                  

                  So…disable them one by one is the next analysis step??

                    @bolish First, try another one

                    find . -maxdepth 2 -exec grep -nwl  .then 2>/dev/null {} +
                    

                    Promises are not always processed by a Promise function, but I also by calling something and then calling .then().
                    Actually I know these bastards for two or three days now, so I’m far from being an expert

                      thx

                      Here is the result

                      pi@MagicPi:~/MagicMirror/modules $ find . -maxdepth 2 -exec grep -nwl  .then 2>/dev/null {} +
                      ./MMM-Remote-Control/node_helper.js
                      ./MMM-Remote-Control/installer.sh
                      ./MMM-BackgroundSlideshowInfo/README.md
                      ./MMM-NotificationTrigger/README.md
                      pi@MagicPi:~/MagicMirror/modules $ 
                      
                      

                      So… Remote Control I believe…
                      I will try to disable it and see what happens.
