I have the same trouble.

[ys-office-llc]

Maybe a bug.

redirect_uri is invalid.

I add a redicret_uri to https%3A%2F%2F（https://）

Example:
https://access.line.me/oauth2/v2.1/authorize?response_type=code&client_id=1654407713&redirect_uri=https%3A%2F%2Fline-login-starter-20200701.herokuapp.com%2Fauth&state=z4327Rb3SiXRDo-D0bUD3toQCixSpVyH68jLL9-S6gE&scope=openid%20profile&nonce=SWFEng3EK6E3HNKyIOa-YT8NW5QIrtqEjYpY2sZoLMI

solved.

It's just a misconfiguration of heroku.

In your https://developers.line.biz/console/channel, select your target channel:

• select LINE login tab, add your redirect url to Callback URL (exp: https://myredirect.local/app/redirect)
• select Basic Settings: at Linked OA, choose your target channel and save.
  Hope it help.

My problem is solved when I click copy buttons (copy callback url, chanel id and chanel secret) and then go to your app on heroku click edit, and paste them
`
For Chanel Id ->click copy

Copy the others and paste them one by one

`
Do not select the texts and paste You should click the copy button instead
