Summary:

First: Thank you SO MUCH for creating this! This is exactly what I need for a project, especially amid the outages and other things going on at OpenSky. I know it was years ago, but it seems to ALMOST still work! I'll submit a PR shortly.

Narrative of the issue:

I have this script running in a Docker container where the CMD runs this script as specified. I did some extensive troubleshooting to the point where the script seemed to be running OK, but the output looks like this (i.e., this is what I see when I run "docker logs" for the container):

Error collecting data for 2024/3/6/1:29

Things I tried & findings:

After some further troubleshooting and research, I created a pared-down, non-looping version of the script (collectDataOneOff.py) to throw a useful error:

Traceback (most recent call last):
  File "/init/collectDataOneOff.py", line 65, in <module>
    track.append(s.heading)
                 ^^^^^^^^^
AttributeError: 'StateVector' object has no attribute 'heading'

Conclusion:

Most likely, OpenSky just changed the name of that attribute from heading to true_track (on further research: yes, it seems they did so at API version 1.3.0 around 2018). Again, I expect to submit a PR for this.
