Can you help me about this error

[Fonfon]

Hi Mykle1,

Indeed by elimination I think I can find the module that generates this error

i try this thanks .
and after if is it a module ?

@fonfon

I had that error a few times, it was always an error in the config.js file. use a Js Linter to help you find the errors.

[Fonfon]

@justjim1220 thanks i use jshint.com no error

[justjim1220]

@fonfon

next thing to try it to npm install in each individual module directory

then npm rebuild in the MagicMagic directory

let me know if that helps!

[Mykle1]

@fonfon

Did you determine which module is causing the error?

[Fonfon]

@mykle1 Thanks mykle1 but no !
for desactivate a module i cut/paste the folder on the desktop then i restart the MM is it the good method ?
because when i have no module its ok no error
only with pir module its good
but after with wunderground or google maps traffic module i have a lot of error or other…
i don’t understand !!
this after the update in 2.4.1.

This is how I disable modules without copying and pasting and moving things around. You can simply add disabled: false, at the beginning of all your config.js entries. true will disable the module.

{
            disabled: false,
            module: 'MMM-EventHorizon',
            position: 'bottom_left',
            config: {
                date: "2018-09-17", // (YYYY-MM-DD)  Date timer will end
                time: "00:01:00", // (HH:MM:SS)    Exact time you want timer to end
                text1: "Lucy's Birthday", // 2 lines of text during timer
                text2: "Tempus Fugit", // 2 lines of text during timer
                endText1: "Lucy is 1 today!", // 2 lines of text when timer ends
                endText2: "What a big girl!", // 2 lines of text when timer ends
            }
        },

@fonfon

no need to cut/paste each module…

you can add

   disabled: false

above each module, like this…

{
    disabled: false,
    module: "clock",
    position: "top_center"
},

then, you can change it to true to shut off the module.

it would be the easiest way to determine which module is causing the issue.
load all your modules back into the config.js,
add the code above,
make all the default modules ‘false’,
and all the rest ‘true’,
refresh your mirror,
if you still get the same issues,
turn off the mirror and your terminal,
maybe even restart your computer,
then open your terminal,
restart the mirror with ‘npm start -dev’
this will give you an error log, find that and post it in here,
this would be easier for us to help you

@mykle1

This is after only 15 min of MM running

@fonfon
One of your modules is using promise pattern but not handling rejection. Usually this is caused by missing some exception handling in module.
I cannot figure out which module is causing that message. You can find which module has problem by disabling or removing module from config.js one-by-one.
Maybe your suspicious module might have SOMETHING.hash in its codes. the error will be caused object SOMETHING is really null. so, when you find which module has the error, tell the module developer the symptom. (S)he will fix it.

[A Former User]

@fonfon
And one more thing.
Most of those UnhandledPromiseRejectionWarning does not give harm to MM’s execution, the real problem is TypeError: Cannot read property 'hash' of null. You should find which module is causing this message.

Start MM with npm start dev. This opens the Developers Tools window. Click “Console” tab at the top of the window. Here you will find any errors. It does not save as a log.

Follow Sean’s suggestion (and mine) that you determine which module is causing the issue. Then paste the errors from that module here.

[Fonfon]

@mykle1 When i start with npm start dev:

@fonfon

Do you get that error with just the default modules?

[Fonfon]

@mykle1 yes with default modules

Above you said with pir module its good . . . .

So now I am confused. I think that perhaps we don’t understand each other. Run MM with ONLY the default modules. If you are having trouble that way then your problem lies with your installation of MM.
