Got "Access to this API is not available for your account" for API "https://api.line.me/v2/bot/dedisco/migration/userId?mid="
We integrated line login in our app. Since two weeks ago, the api "https://api.line.me/v1/profile" retired, and we had to switch to https://api.line.me/v2/profile. The problem is, we can no longer get mid from this API, but userid instead. And we need to convert the existing users' mids to their userids. We followed the guide https://developers.line.biz/en/docs/line-login/converting-mid-to-userid/, but when we tried to call "https://api.line.me/v2/bot/dedisco/migration/userId?mid=", we got response "Access to this API is not available for your account". How to fix this issue? We are urgent to let the existing users log into our app, please kindly help, thanks!
