uploading gpx converted from fit fails

[chri2]

After having the problem of not being able to upload a .fit (#21) taken from a Garmin Forerunner 165 I converted that fit to a .gpx using gpsbabel: gpsbabel -i garmin_fit -f 2024-11-20-09-55-53.fit -o gpx -F 2024-11-20-09-55-53.fit.gpx

fittrackee-uploader shows a map with the track as expected. Pressing the upload button I get the following error:

same issue for Garmin Edge 830

for both devices the upload of the gpx works when using the fittrackee website in a browser
