MMM-NYC-Transit Module (Black Screen)

sdetweil

@JediJah open the developers console, ctrl-shift-i on the mirror keyboard, select the tab labeled console, and put nyc in the filter field

are there any errors shown, typically red text

JediJah

@sdetweil Thanks for the response. There are no errors shown.

sdetweil

@JediJah ok, take the nyc out of the filter field… black screen means the UI died… so its gotta be there somewhere

if u add

disabled: true,

to the module definition
right after the module name

{
 module:'MMM-NYC-Transit',
 disabled: true,                                 // add this line
 ...
 config: {
 }
}

does the black screen go away?

JediJah

I realized I have since removed the config. I will re-add and check again.

JediJah

@sdetweil I added the module to config, disabled!
The Mirror loads as normal.
Something I find weird is even with the module disabled, its header is still shown.

sdetweil

@JediJah it is not disabled according to the picture
and the screen is not black

if it were disabled, NOTHING about the module would show…

same as if that entry was not in config.js at all

JediJah

@sdetweil I figured thats why I said it was weird.

This is what the module looked like in my config

  {
              module: 'MMM-nyc-transit',
              disabled: "true",
              position: "bottom_right",
              header: "Next Train",
              config: {
                     apiKey: '9b76b0b756f7f9a76d4fe883075c00cf',
                                displayType: 'list',
                                mtaType: 'train',
                                stations: [
                                        {
                                        stationId: 95,
                                        walkingTime: 5,
                                        dir: {
                                                upTown: false,
                                                downTown: true
                                             }
                                        },
                                        {
                                        stationId: 95,
                                        walkingTime: 5,
                                        dir: {
                                                upTown: true,
                                                downTown: false
                                             }
                                        }
                                        ],
                                updateInterval: 300000
                }
                },

These are the steps I just tried…
recreated original circumstances that caused black screen (added Module to config) and yes the black screen still exist.

I assume that means there is issue with module config settings.

I tried to launch the Dev console, but it did not launch in same page as black mirror screen but a white page.

I will wait for your response before making changes to config.js file again.

@JediJah said in MMM-NYC-Transit Module (Black Screen):

          disabled: "true",

no, i said

disabled: true

no quotes

how do you start MM? using pm2 or manually

JediJah

@sdetweil Aww OK will adjust

JediJah

@sdetweil pm2

After adding disabled: true

Got "Please create a config file " error

sdetweil

@JediJah come on , the original instructions said

disabled: true,

just about any new line requires a comma at the end

JediJah

@sdetweil Yeah that was my bad… the mirror loads now without the module…

@JediJah how do you start MM? using pm2 or manually

I did clone the repo as required??

@JediJah said in MMM-NYC-Transit Module (Black Screen):

Cannot find module ‘mta-realtime-subway-departures’

but it looks like you didn’t follow the module install instructions

1. clone this repo with the following command: git clone https://github.com/Elaniobro/MMM-nyc-transit.git
2. install all the npm modules with either yarn install or npm install

to do 2, you need to change into the module folder

git clone ......
cd MMM-nyc-transit
npm install

JediJah

@sdetweil
Looks like I ran npm install on modules dir.

@sdetweil Thank you immensely for you help. It is running now.
