@aws-sdk/client-cloudfront ListDistributionsCommand returns incorrect "HttpVersion" value

• I've checked AWS Forums and StackOverflow.
• I've searched for previous similar issues and didn't find any solution.

Describe the bug

I am working on integrating the Cloudfront service with our internal system.

However, I found that the ListDistributionsCommand returns the incorrect "HttpVersion" value.

It returns "HTTP2and3" instead of "http2and3".

SDK version number

@aws-sdk/client-cloudfront@3.477.0

Which JavaScript Runtime is this issue in?

Node.js

Details of the browser/Node.js/ReactNative version

v20.9.0

Reproduction Steps

1. Log in to the AWS CloudFront dashboard.
2. Create a new distribution; Make sure to select both HTTP/2 and HTTP/3 in the "Supported HTTP versions" section, then submit to create.
3. Write a minimal node.js code with @aws-sdk/client-cloudfront to send a ListDistributionsCommand request. Check the response to reproduce the bug.

Observed Behavior

This is what I got from aws server:

{
    "$metadata": {
        "httpStatusCode": 200,
        "requestId": "1a551a4f-8a33-4a57-9186-ed4461621524",
        "attempts": 1,
        "totalRetryDelay": 0
    },
    "DistributionList": {
        "Marker": "",
        "MaxItems": 100,
        "IsTruncated": false,
        "Quantity": 1,
        "Items": [
            {
                "Id": "E39HM9L49VTJZO",
                // ... some fields
                "HttpVersion": "HTTP2and3", // 👈 this is wrong, should be "http2and3"
                // ... some fields
            }
        ]
    }
}

Expected Behavior

The value of the "HttpVersion" field should be "http2and3" instead of "HTTP2and3".

This value is incorrect because it does not align with two things:

• It does not follow the type declaration of /node_modules/@aws-sdk/client-cloudfront/dist-types/models/models_0.d.ts
• It does not follow what GetDistributionCommand returns (it returns the right value "http2and3")

Possible Solution

No response

Additional Information/Context

For reference purpose, this is what defined in /node_modules/@aws-sdk/client-cloudfront/dist-types/models/models_0.d.ts:

export declare const HttpVersion: {
    readonly http1_1: "http1.1";
    readonly http2: "http2";
    readonly http2and3: "http2and3";
    readonly http3: "http3";
};

Hi @Jianru-Lin ,

Thanks for reaching out. If you didn't know the AWS SDKs are code generated from the API models defined by each service team. In this case, the Cloudfront team has modeled this enum with all lowercase values as seen in the internal API model that each SDK holds.

I would have to reach out to the Cloudfront service team to either change the enum value or correct the value they return.

Aside from spotting the discrepancy, is there anything here that is blocking you?

Thanks,
Ran~

According to service team, this change will break customers that already take a dependency on the current state of this API.

Since there's no action item for SDK team and this repo is dedicated for JS SDK related issues, we're going to close this now.
