SDK doesn't parse endpoint connection state correctly

[HenryS1]

Describe the bug

I have a vpc endpoint connection with state pending acceptance, but when I access the state value in the SDK result it returns UNKNOWN_TO_SDK_VERSION. It seems that the problem is caused by the SDK expecting the state value to have pascal case while it actually has camel case. When I parse the response from a string manually using the vpcEndpointStateAsString method with a camel case parser it works for me, but I'd like to be able to used the SDK enum values instead of parsing the string myself. There is a related issue in the old rust AWS SDK repo here aws/aws-sdk#360. This is the state enum in the service-2.json file.

    "State":{
      "type":"string",
      "enum":[
        "PendingAcceptance",
        "Pending",
        "Available",
        "Deleting",
        "Deleted",
        "Rejected",
        "Failed",
        "Expired",
        "Partial"
      ]
    }

As I understand it this is used to generate the string representation of the state enum used when the sdk parses the value. I imagine that the solution is for this enum to be updated to match the values used by the API.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

I expected the SDK to return the PENDING_ACCEPTANCE value of the State enum for a VpcEndpointConnection with state pending acceptance that I looked up on the API.

Current Behavior

The SDK returned UNKNOWN_TO_SDK_VERSION.

Reproduction Steps

Create a vpc endpoint connection and use the describeVpcEndpointConnections method to query it from the AWS API. The state will be incorrectly parsed as UNKNOWN_TO_SDK_VERSION.

Possible Solution

It seems to me that the file service-2.json is used in codegen for the SDK. If that's correct a possible solution may be to update the values of the State enum for a VpcEndpointConnection to be camel case so that they match the values returned by the API.

Hi @HenryS1,

Thanks for reporting the issue. awslabs/aws-sdk-rust#619 was the original issue which was reported to the service team owning the API.

Modeled value fixes are to be done at service-level which would then flow down to the respective SDKs, updating the service-2.json in this case.

I will follow-up with service team to see if I can get some traction on this issue.
