Hi @marcosbianchi have you tried a different region by setting the environment variable?

Yes, tried changing it to EU but received this:

Okay, looks good. Can you see current measurements in the LibreLink Up app using the same credentials?

marcosbianchi commented 1 year ago

Yes, app works fine with those credentials.

I have the same experience after updating to 2.4.0 due to the librelink update.

I have this experience too. Yes, I can see readings in the LibreLinkUp app. I'm in the UK using the EU2 region (as advised in the log). I'm using the docker variant.

According to https://gist.github.com/khskekec/6c13ba01b10d3018d816706a32ae8ab2 measurementData.connection.glucoseMeasurement represents the last glucose measurement.

The error can happen when there are no readings whatsoever in LibreLinkUp, or when glucoseMeasurement is not passed by the server for whatever reason.

Could probably add some checks to keep retrying instead of crashing the server.
