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”.
The add-on file looks fine to me, also the AnkiWeb upload feature seems to be working normally.
If the Wi-Fi speed is slow such errors may occur during the process. If so you may need to try again repeatedly or switch to a different connection.
Occasionally the chosen file may not load properly. If so reselecting the file or reloading the page may resolve the issue.
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.
Adding a manifest.json file makes it possible to distribute the add-on directly, it’s common when developers want to release a pre-release version. e.g.
Download the .ankiaddon file and open it with a double-click, or install it from the “Install from file” menu in the Anki add-ons management screen. (Please note that you cannot install the file by dragging and dropping it into Anki.)
