Heroku Error reading data: "Cannot read properties of undefined (reading 'data')" / Minimum Version : 4.12.0

after working perfectly for months, i suddenly have trouble reading data from the libre site.

I have the app running on heroku, already restarted all dynos multiple times, but no difference.

2024-11-25T21:35:01.211467+00:00 app[worker.1]: [error]: getting libreLinkUpConnection: Cannot read properties of undefined (reading 'data')

I then tried to just set up another instance, but (even after configuring the env-variables prior) i get the error:

No app.json located in the repo URL provided.

I tried the usual stuff (checking for ToS Update, restart). Am i missing something?

Thanks you all for you effort <3

The reason it suddenly stopped working is that you're using an outdated version of the Uplink image. You need to run a newer version – the current one is [email protected] – which includes the correct version required by the server. The requests send a version number defined in line 87 of the index.ts file, which you could manually adjust, but there's no guarantee it will work properly. Upgrading to the latest version is the better solution. Can you update your old instance?

The second problem seems to be caused by a faulty setting – but I'm not very familiar with Heroku, so I can't provide specific instructions. Have you referred to a manual or guide for setting up the second instance?

Thanks for pushing me to the right direction. Tbh i was not that into Heroku aswell and just deployed it in 2023 without thinking about updates. It just worked back then :)

Well.. lesson learned: i now redeployed it in heroku with the current version and it now works again.

Thanks again!
