Identity not found in GetCredentialsForIdentityRequest

Question

Hi all,  
I created a SAML Identity Pool in Cognito and tried to get a JWT from a Java fat client.

```
AmazonCognitoIdentity  client=AmazonCognitoIdentityClientBuilder.standard()
                                  .withRegion(Regions.EU_CENTRAL_1)
                                  .build();
    
    Map logins = new HashMap();
    logins.put("arn:aws:cognito-identity:eu-central-1:123456789:identitypool/eu-central-1:fxxxxx-bxxx-4xxx-bxxx-1xxxxxxx3", "I wish I was a base64 SAML Assertion");
    
    GetCredentialsForIdentityRequest request=new GetCredentialsForIdentityRequest()
                                                 .withIdentityId("eu-central-1:fxxxx-bxxx-4xxx-xxx-xxxxb6f3")
                                                 .withLogins(logins);
   
    GetCredentialsForIdentityResult result= client.getCredentialsForIdentity(request);
```

Gave me

```
 com.amazonaws.services.cognitoidentity.model.ResourceNotFoundException: Identity 'eu-central-1:fxxxx-bxxx-4xxx-xxx-xxxxb6f3' not found. (Service: AmazonCognitoIdentity; Status Code: 400; Error Code: ResourceNotFoundException;
```

I already red about setting the region which I did but without any effect.  
We double checked the identity pool id  
Any Ideas what could went wrong with my call?  
  
Thanks in advance

Hi,  
  
the secret has been unveiled. To connect as an anonymous user to a cognito identity pool you need these few lines of code:

```
AmazonCognitoIdentity  client=AmazonCognitoIdentityClientBuilder
                                  .standard()
                                  .withRegion(Regions.EU_CENTRAL_1)
                                  .withCredentials(new AWSStaticCredentialsProvider(new AnonymousAWSCredentials()))
                                  .build();

Map logins = new HashMap();
    logins.put("arn:aws:iam::1234567890:saml-provider/my-saml-provider", "A base64 SAML response");
    
    GetIdRequest request = new GetIdRequest()
                                                 .withIdentityPoolId("eu-central-1:7xxxxx-cxxx-xxxx-xxx-xxxxx")
                                                 .withLogins(logins);
   
   GetIdResult result= client.getId(request);
```

In the logins map you have to put the arn of the SAML provider you created in IAM using the SAML Metadata.
