Flight Log Analyzer Error in extracting GPS and Attitude Data
Hello, I am trying to import a ulog file from a PX4 SITL flight of a UAV performed in Qgrouncontrol. The ulog file works fine and the GPS data and everything else is available when I use the PX4 online flight reviewer (https://review.px4.io/plot_app?log=b0a85256-2690-49bb-8b93-a76311c32c86), however, when I try importing the downloaded ulog file (top right on page you can download it as well), the flight log analyzer app does not display any 2D map. It lists the flight modes and their timestamps, but when I hover over the map view, I get a "Error in extracting GPS and Attitude Data" message.
When importing the ulog from into the workspace using ulogreader there is a long list of topics, and the GPS position seems to be included, but when opening the signal browser after importing the ulog file into the flight log analyzer, many of the topics seem to not have been imported?
Importing the ulog file from the tutorial works, so I am assuming that there is something wrong with my ulog file format/the way the flight analyzer is trying to read the message fields, but I am unsure what exactly the problem is. If anyone has any ideas please let me know
