Transit module stopped working

[nipper2000h]

Hello,

I have been successfully using the MMM-nyc-transit module the past few weeks without issue but it stopped working yesterday morning. This is the only module in my mirror that is having an issue and it seemed to start randomly. I’ve tried reinstalling the module on a fresh image of MM but the module still did not work. While config check has returned no errors, npm logs reveal this issue. Could someone please help me to decipher the error and work towards a resolution? ```

Thank you.

It also doesn’t work for me either, but my logs are empty :(

You can see the “Next Train” at the top but no trains.

@elliob

Thanks for the reply. I guess it’s nice knowing I’m not the only one having trouble. Did you just install it or were you using it beforehand?

Here’s this project’s config for whatever it’s worth.

@nipper2000h looks like a data change from the provider API

2020-06-30 09:41:59.974] [ERROR]  (node:882) UnhandledPromiseRejectionWarning: Error: Error: Illegal group end indicator for Message .transit_realtime.FeedMessage: 7 (not a group)
0|mm       |     at /home/pi/MagicMirror/modules/MMM-nyc-transit/node_helper.js:106:15

[nipper2000h]

@sdetweil Thank you for the info. You helped me out the first time I had an issue too, I’m very appreciative of your help once again. Does that mean the next step is too hope the contributor releases an update?

[sdetweil]

@nipper2000h yes, probably. I would post an issue to the module GitHub page to inform them

[nipper2000h]

@sdetweil Thanks again.

[Elaniobro]

@sdetweil what makes you think the API changed? ( I am the author, and am looking into it now)

[sdetweil]

@Elaniobro I posted a couple messages back the error info. node_helper line 106 called something which threw an error

2020-06-30 09:41:59.974] [ERROR]  (node:882) UnhandledPromiseRejectionWarning: Error: Error: Illegal group end indicator for Message .transit_realtime.FeedMessage: 7 (not a group)

[elliob]

@sdetweil how did you get to error message? What’s the CLI?

[sdetweil]

@elliob it was in the pm2 log in the 1st post of this topic

[nipper2000h]

@elliob I’m using pm2 to start MM so from the root directory:

pm2 logs mm

[sdetweil]

@nipper2000h the logs are stored in the users .pm2 folder. doesn’t matter where I issue the pm2 commands

[Elaniobro]

The module is getting the data, but its not updating with the this.updateDom method. I am not sure if this was deprecated or not. Looking into it.

[sdetweil]

@Elaniobro how does it use this.updateDom()

[Elaniobro]

@sdetweil Its called in the socketNotificationReceived() here:
https://github.com/Elaniobro/MMM-nyc-transit/blob/master/MMM-nyc-transit.js#L358-L360

[sdetweil]

@Elaniobro where is self set.? and fadeSpeed?

[Elaniobro]

@sdetweil They aren’t, they can be removed. Issue I am seeing is the payload is not populated indo the getDom()

I am setting this.result = payload which on intitial load/start of the module is undefined, which is expected, since the API promise has not been fulfilled. Later on, the socketNotificationReceived() recieves a payload which is set to this.result but in the getDom() var data = this.result is never updated.

I am unsure of where/what caused this breakdown, as last time I touched the code was Apr 30. This is leading me to believe something changed in Core, but I am unaware of what that might be.

[sdetweil]

@Elaniobro are u debugging w the developers window?
you can walk thru the code as it executes
ctrl-shift-i and select the sources tab, use the tree on the left to find your module, and it’s source

then click the left edge of a line of code u want to examine, and a stop will be added.

usually a problem like this is because the ‘this.’ pointer doesn’t point where u think it does.

sorry, I am in hospital for a few more days and cannot debug from here

[Elaniobro]

@sdetweil Thank you for your feedback. I am/was already debugging in the manner you mentioned. I was able to resolve the bug(s), but now I am still not seeing any data. My best guess is somewhere along the fetch of the data something changed or broke. The application is returning data, but the response is empty.

payload = [{ downTown: [] }, { upTown: [] }]

For some reason, just not getting any data :/

I am still digging in.
