[BUG] Cannot verify pjsk account

[Lapis0875]

When I try to bind my pjsk account, it constantly fails with following error.

To Reproduce

1. Login using discord
2. Go to user page
3. Click 'bind' button below the text 'Sekai Profile'
4. Input my pjsk account id
5. Write the generated token in my pjsk profile
6. Leave profile in game
7. Click 'Verify' button

Expected behavior My pjsk account should be bound.

Screenshots

Browser (please complete the following information):

• OS: Windows 10
• Browser Whale (based on chromium)
• Version 3.18.154.7

Possible cause and/or solution I don't know how the api is implemented, so I could guess followings :

• api cannot retrieve text in my profile's textbox
• somehow verification token is expired

I'm also getting this error, but when I inspected the request it returned a 500 (Internal Server Error), which seems to be a server issue. Could you devs look into this? (JP server for me)

Edit: I saw a success request but the app return an error, and then after reloading it shows the token-not-exist error.
