Updating User.UserAttributes on AWS Pinpoint - amazon-web-services

Question

I cannot seem to update pre-existing UserAttributes on a user "73". I am not sure if this behaviour is to be expected.
Map<String, List<String>> userAttributes = new HashMap<>();
userAttributes.put("Inference", Arrays.asList("NEGATIVE"));
userAttributes.put("Gender", Arrays.asList("M"));
userAttributes.put("ChannelPreference", Arrays.asList("EMAIL"));
userAttributes.put("TwitterHandle", Arrays.asList("Nutter"));
userAttributes.put("Age", Arrays.asList("435"));
EndpointUser endpointUser = new EndpointUser().withUserId("73");
endpointUser.setUserAttributes(userAttributes);
EndpointRequest endpointRequest = new EndpointRequest().withUser(endpointUser);
UpdateEndpointResult updateEndpointResult = pinpoint.updateEndpoint(new UpdateEndpointRequest()
.withEndpointRequest(endpointRequest).withApplicationId("380c3902d4ds47bfb6f9c6749c6dc8bf").withEndpointId("a1fiy2gy+eghmsadj1vqew6+aa"));
System.out.println(updateEndpointResult.getMessageBody());

#David.Webster,
You can update user-attributes of Amazon Pinpoint endpoint using the below Java code snippet which I have tested to be working :
public static void main(String[] args) throws IOException {
// Try to update the endpoint.
try {
System.out.println("===============================================");
System.out.println("Getting Started with Amazon Pinpoint"
+"using the AWS SDK for Java...");
System.out.println("===============================================\n");
// Initializes the Amazon Pinpoint client.
AmazonPinpoint pinpointClient = AmazonPinpointClientBuilder.standard()
.withRegion(Regions.US_EAST_1).build();
// Creates a new user definition.
EndpointUser jackchan = new EndpointUser().withUserId("73");
// Assigns custom user attributes.
jackchan.addUserAttributesEntry("name", Arrays.asList("Jack", "Chan"));
jackchan.addUserAttributesEntry("Inference", Arrays.asList("NEGATIVE"));
jackchan.addUserAttributesEntry("ChannelPreference", Arrays.asList("EMAIL"));
jackchan.addUserAttributesEntry("TwitterHandle", Arrays.asList("Nutter"));
jackchan.addUserAttributesEntry("gender", Collections.singletonList("M"));
jackchan.addUserAttributesEntry("age", Collections.singletonList("435"));
// Adds the user definition to the EndpointRequest that is passed to the Amazon Pinpoint client.
EndpointRequest jackchanIphone = new EndpointRequest()
.withUser(jackchan);
// Updates the specified endpoint with Amazon Pinpoint.
UpdateEndpointResult result = pinpointClient.updateEndpoint(new UpdateEndpointRequest()
.withEndpointRequest(jackchanIphone)
.withApplicationId("4fd13a407f274f10b4ec06cbc71738bd")
.withEndpointId("095A8688-7D79-43CE-BDCE-7DF713332BC3"));
System.out.format("Update endpoint result: %s\n", result.getMessageBody().getMessage());
} catch (Exception ex) {
System.out.println("EndpointUpdate Failed");
System.err.println("Error message: " + ex.getMessage());
ex.printStackTrace();
}
}
}
Hope this helps
