Hello! I made this add-on for my partner who is in medical school and I was trying to upload it to AnkiWeb via https://ankiweb.net/shared/upload but I keep getting a “try again later” error. I am getting a 400 error from /svc/shared/upload-addon with no message except “try again later”. Source co…

I never uploaded an addon before but cannot imagine that filling out that form would cause a bad request error . Maybe try a different internet browser and try to turn off all addons in your browser.

Yeah the 400 error makes me think there is something wrong in my submission (bad request), but I confirmed my .ankiaddon is the right type. Maybe try a different internet browser and try to turn off all addons in your browser. Didn’t work :confused:

I have tried setting this to a bunch of different options but no luck.. Maybe I just don’t understand what its asking for here?

[image] Shigeyuki: There is a restriction preventing add-ons from being uploaded if the user’s account is too new, but in that case a different error should appear instead of a 400 so it doesn’t seem related. This is my best guess, my account is very new.

As far as I know, that should be the lowest and highest version of Anki that you have tested it with and know it works.

Can you share the add-on zip here? We might be able to figure out something.

That would be really appreciated! Here it is: Release v1.0.0 · n3s-online/anki-break-reminder · GitHub

This might not be the best error message to indicate this – but isn’t the version a problem?
