pyulog not extractting vehicle_air_data

[Ambika Verma]

Hi

I trying to convert ulog data I have to csv using pyulog.
In a few u log files, if I use flight review tool, I can see the barometric data being plotted. Here is the link to the logs - https://logs.px4.io/plot_app?log=b852b2d8-93e1-4ae2-b204-6ffa89453f86

But when I try to convert it to csv using pyulog I dont see a file associated with vehicle_air_data.
For some other files it works fine.

Not sure what the issue might be since flight review is able to plot it.
Any suggestions?
Thanks!

Hi
The log is from an older version of the Firmware and the baro data is in the sensor_combined topic.
