LineLoginApi.getLoginIntent throws javax.crypto.KeyGenerator.generateKey exception

[kightsonsanom]

What did you do?

Tried to create login intent:

val authParams = LineAuthenticationParams.Builder()
            .scopes(listOf(Scope.PROFILE, Scope.OPENID_CONNECT, Scope.OC_EMAIL))
            .build()

val intent = LineLoginApi.getLoginIntent(context, "mychannelId", authParams)

The issue happens only to some users, in most cases it works fine. Happens on different devices and Android version, we couldn't find any relation between them.

What did you expect?

Intent created properly

What happened actually?
