Issue

On some Android devices, the application crashes after passing the authentication procedure. Works correctly on most devices.

Config:

const { AUTH_CLIENT_ID, AUTH_CLIENT_SECRET, AUTH_REALM, AUTH_URL, AUTH_APP_SCHEME } = Config;

export function getAuthConfig(): AuthConfiguration {
    return {
        issuer: `${AUTH_URL}/realms/${AUTH_REALM}`,
        clientId: AUTH_CLIENT_ID,
        clientSecret: AUTH_CLIENT_SECRET || undefined,
        redirectUrl: `${AUTH_APP_SCHEME}:/callback`,
        scopes: ['openid'],
    };
}

Error:
