Cognito AdminCreateUser, AdminDeleteUser, AdminDisableUser returning tcp no such host error

[jasonkofo]

Describe the bug

All calls into the cognito identity provider are falling with no such host TCP errors. Running the individual commands from the AWS cli produces the correct results, however, calls from the SDK do not work.

Expected Behavior

I expect to be able to progress with cognito operations.

Current Behavior

operation error Cognito Identity Provider: AdminDisableUser, exceeded maximum number of attempts, 3, https response error StatusCode: 0, RequestID: , request send failed, Post \"https://cognito-idp.eu-west-1_XrdhhKGBb.amazonaws.com/\": dial tcp: lookup cognito-idp.eu-west-1_xxxxxxxxx.amazonaws.com: no such host

Reproduction Steps

func (x *pfCognitoClientPoolManagerV2) createCognitoUser(ctx context.Context, user RemoteUser) error {
	attrs := make([]cognitotypes.AttributeType, 0, 2)
	media := make([]cognitotypes.DeliveryMediumType, 0, 2)

	attrs = append(attrs, cognitotypes.AttributeType{Name: utils.String("email"), Value: user.Email})
	media = append(media, "EMAIL")
	if user.Mobile != nil {
		attrs = append(attrs, cognitotypes.AttributeType{Name: utils.String("phone_number"), Value: user.Mobile})
		media = append(media, "SMS")
	}

	createuserinput := &cognito.AdminCreateUserInput{
		UserPoolId:     &(*x).userPoolId,
		Username:       user.Username,
		UserAttributes: attrs,
		MessageAction:  "SUPPRESS",
	}
	_, err := x.provider.AdminCreateUser(ctx, createuserinput)
	if err != nil {
		return fmt.Errorf("could not create cognito user: %v", err.Error())
	}
	return nil
}

Possible Solution

No response

Additional Information/Context

I am calling this API from my personal machine, which produces the same issues as what was seen from AWS lambdas

Current location: Stellenbosch, Cape Town, South Africa Cognito Region: eu-west-1

Thanks for opening this issue,

I'm not sure why you are running into this error but my guess would be that your client is not set up correctly. Its hard to know because you seem to be wrapping it with pfCognitoClientPoolManagerV2 struct and I'm not sure what your provider field looks like since that part is missing.

Also I have noticed you are using createuserinput := &cognito.AdminCreateUserInput{ Are you prefixing your import as cognito? because it is supposed to be createuserinput := &cognitoidentityprovider.AdminCreateUserInput{

Here is my working code:

import (
	"context"
	"fmt"
	"github.com/aws/aws-sdk-go-v2/aws"
	"github.com/aws/aws-sdk-go-v2/config"
	"github.com/aws/aws-sdk-go-v2/service/cognitoidentityprovider"
	"log"
)

func main() {
	cfg, err := config.LoadDefaultConfig(context.Background(), config.WithRegion("us-east-1"))
	if err != nil {
		log.Fatalf("unable to load SDK config, %v", err)
	}

	client := cognitoidentityprovider.NewFromConfig(cfg)

	createuserinput := &cognitoidentityprovider.AdminCreateUserInput{
		UserPoolId:    aws.String("userPoolID"),
		Username:      aws.String("Oscar"),
		MessageAction: "SUPPRESS",
	}
	res, err := client.AdminCreateUser(context.Background(), createuserinput)
	if err != nil {
		fmt.Errorf("could not create cognito user: %v", err.Error())
	}

	fmt.Println(*res.User.Username)
}

outputs: oscar

Let me know if that helps. Thanks, Ran
