Facebook returns email address with ‘\u0040’ Unicode symbol instead of ‘\u{0040}’ or ‘@’, it causes an exception during the decoding. So there is the workaround:  
…  
guard let body = response.body else {  
throw Abort(.internalServerError)  
}  
var content = String(buffer: body)  
content = content.replacingOccurrences(of: “\u0040”, with: “@”)  
let data = Data(content.utf8)  
let userInfo = try JSONDecoder().decode(FacebookUserInfo.self, from: data)  
return userInfo
