gets me Error while fetching departures (for module Instance S+U Gesundbrunnen): TypeError: Cannot use 'in' operator to search for 'bg' in undefined, preventing rendering of this instance. The other one works.

This error seems to occur in node_helper.js at Lines 141-147.

It faults, when the variable color is undefined, which may only happens if the type of line is suburban, subway, tram or regional where we look up the colors in a table. I had the same problem but with the tram line 18 (which is not defined in the lineColors.tram array.
I am tbh not sure where you got the line colors and available lines from exactly but seems like there are some things missing.

I will open up a pull request to address this.

Thanks for finding this. The colors come from this module: https://github.com/derhuerst/vbb-line-colors
If there are missing colors, maybe this is an error which needs to be fixed in this module

[deg0nz]

Yeah. I think you found a bug in vbb-line-colors. It seems that there is a tram line 19 instead of 18 in the tram array, but according to Wikipedia, there only is a line 18.

Now, we just need to know, what is going on around Gesundbrunnen to address @berlincount's error. Obviously, there is another line missing that has a stop there. Tram 18 seems not to have a stop there...

[dschemp]

I am guessing there is some sort of regional train missing?

The module does not seem to reference official sources right now (it's an open issue). Might look into it aswell.

I don't know, but I have an idea, how we can find this out easily. Just take your approach of #61 and make the colors more obvious.

[dschemp]

It's the FEX! It runs over Hbf and Gesundbrunnen.
Your version of vbb-line-colors does not yet have the FEX included.

I have commited an update aswell.

[dschemp]

I've created a PR over on vbb-line-color with the latest changes. If you want, you can watch and update your app when the PR gets approved and the package updated.

[deg0nz]

This issue should have been fixed with #61.

oh, wow - thank you! :)
