Amplify Federated Sign In not returning Email for Facebook

I'm using AWS Amplify to add social signing. With google I'm getting the email of the user but it's missing in facebook.

This is my code:

  federatedSignIn(provider: any): void {
    switch (provider) {
      case 'facebook':
          console.log("Authenticating using Facebook");
          Auth.federatedSignIn({ provider: CognitoHostedUIIdentityProvider.Facebook });
          break;
      case 'google':
        console.log("Authenticating using Google");
        Auth.federatedSignIn({ provider: CognitoHostedUIIdentityProvider.Google });
        break;
    }
     
  }

This is what the "Pre sign-up" Lambda sees as an event.

{
    "version": "1",
    "region": "us-east-1",
    "userPoolId": "us-east-xxxxxx",
    "userName": "Facebook_123456",
    "callerContext": {
        "awsSdkVersion": "aws-sdk-unknown-unknown",
        "clientId": "123456abcd"
    },
    "triggerSource": "PreSignUp_ExternalProvider",
    "request": {
        "userAttributes": {
            "email_verified": "false",
            "cognito:email_alias": "",
            "phone_number_verified": "false",
            "cognito:phone_number_alias": ""
        },
        "validationData": {}
    },
    "response": {
        "autoConfirmUser": false,
        "autoVerifyEmail": false,
        "autoVerifyPhone": false
    }
}
