You’re missing a } here

{
              module: "MMM-WienerLinien",
              position: "top_left",
              config: {
                   api_key: "xxxxxxxxxxx",
                   stations: ["142", "141"],
},

should be

{
              module: "MMM-WienerLinien",
              position: "top_left",
              config: {
                   api_key: "xxxxxxxxxxx",
                   stations: ["142", "141"],
              }
},

Could be other issues, but check that out first :)

Also, it’s a good idea to remove your personal API codes when sharing your config file(s).

Thank you @in_a_days
I copied your answer into the right place, but the screen stays black.

@kurt

You’re welcome, did you re-start the mirror program after changing the config file?

[kurt]

@in_a_days
Yes with strg R on the raspi

@kurt

Hmm. I’ll test your config.js on my system and see if I can isolate the problem.

[kurt]

@in_a_days
wow thanks a lot

Did you run npm install in the MMM-WienerLinien folder?

[kurt]

@yawns

@kurt

From a new terminal session:

cd MagicMirror/modules/MMM-WienerLinien

npm install
