Issues with uploading a world from Aternos to Minehut

[Spoingus]

I'm trying to switch from Aternos to Minehut and I'm trying to upload the .zip world file to the "Upload World" option under the "World" tab. When I try uploading the .zip file, I get a message saying "An error occurred. Please try again." I tried extracting all and uploading the folder itself but it looks like I'm unable to upload folders as well. I then tried deleting the world folder under the "File Manager" tab but when I tried uploading the world folder from Aternos, I was still unable to upload folders.

Does anyone have any idea as to how I can switch from Aternos to Minehut?
