Cant upload large .gpx

[beretor]

Hello

Super nice project.

I cant upload a large .gpx (25Mo). I suspect this is the expected behaviour but there is little info about it. (There is a small warning icon next to the file but no clear info about it)

I kept the max_total_size property of the drag&drop nicegui.upload element to None, so it shouldn't be a problem. But sometimes it fails to upload the file... Most of the time, clearing it and feeding it again works, give it a try!

I should add a clearer warning about it (or write a github issue on nicegui's repo)

Can you send me the GPX ?

Understood. I tried a few times and it still fails. it doesnt even start.

here is the gpx: https://drive.google.com/file/d/1y4Du9VE8jJe6BkkTUvoo9Ohgzueo7QtR/view?usp=drive_web

What a race!! :exploding_head:

I can't reproduce the error you get during the upload... I'd recommend to close all the tabs of your browser and restart the app.

I didn't expected such large tracks, when i ran it the app had issues because of the large number of Digital Elevation Model tiles required to represent the background.

I'll find a way to optimize the memory footprint :eyes:

yes. wrote the issue just to be able to flex ;-)

joke aside, you were correct about restarting chrome. now it uploads but indeed crashes while trying to display it
