User pool does not exist

I'm trying to connect to aws cognito from a java backend, but when it comes to testing it inside AWS Lambda, it throws me an exception with the following message:   

"errorMessage": "User pool XXXXX does not exist. (Service: AWSCognitoIdentityProvider; Status Code: 400; Error Code: ResourceNotFoundException; Request ID: -------------)"

The credentials that I have entered are correct, because I have tested them in a python code and it works correctly.

this is the code with which I made the connection:

private AdminInitiateAuthRequest buildAuhtRequest(String email, String password){
    Map<String,String> authParams = new HashMap<String,String>();
    authParams.put("email", email);
    authParams.put("password", password);

    return new AdminInitiateAuthRequest()
            .withAuthFlow(AuthFlowType.ADMIN_NO_SRP_AUTH)
            .withAuthParameters(authParams)
            .withClientId(credentials.getClientId())
            .withUserPoolId(credentials.getPoolId());
}

and this is the class of credentials, although it is super simple:

public class CognitoClientCredentials {

    private String poolId = "xxxxxxxxx";
    private String clientId = "xxxxxxxxxxxxxxxx";

    public String getPoolId(){
        return this.poolId;
    }

    public String getClientId(){
        return this.clientId;
    }
}

I had multiple AWS profiles setup, so I had to change my default one to be the AWS instance I wanted to connect to and that worked

This answer is for someone who could be having an user pool related error. Such error started to appear to me after I changed the verification type from 'code' to 'link' in AWS Cognito. The issue got solved by just setting up a domain name in the 'App Integration' tab in my user pool settings. This thread helped me to solve my issue -> https://github.com/amazon-archives/amazon-cognito-identity-js/issues/512 enter image description here

What happened to me was...

the AWS.Config grabbed my profile from my Windows 10 user account (.aws/credentials).

So, programatically I had to modify the AWS.config.credentials

It's possible that locally you have already setup the aws environment with a default region, access key and access secret; while you lambda role is not authorizes to handle that Cognito Pool that you are specifying. Try to augment the permissions of you lambda role.

Set the region and try so your function identify which region to check under the cognito.
