The MM works perfectly, but i don’t know why i’ve this message.
Could you help me ?

Thank you :) !

[selyjohns]

Solved, please see issue on github.
My fault :)

[sdetweil]

@selyjohns I don’t know why either.

this is likely the updatenotification module

edit the config.js and add

disabled: true,

after the line
module: “updatenotification”
make sure there is a comma on the end of the module line

{
   module:"updatenotification",
    disabled: true
},

@sdetweil
Hi sam,

Thank you for this quickly response.
I confirm, move this module to disabled and i don’t have UnhandledPromiseRejectionWarning anymore…

But i think this is not a good solution ?

[sdetweil]

@selyjohns but we confirmed it is that module… I would open an issue in the github repo for MagicMirror

[bugsounet]

@sdetweil I think it’s an sudoers ;)
