DescribeVpcEndpoints returns the State value in lowercase instead of UpperCamelCase

[rajramo61]

Acknowledgements

• I have searched (https://github.com/aws/aws-sdk/issues?q=is%3Aissue) for past instances of this issue
• I have verified all of my SDK modules are up-to-date (you can perform a bulk update with go get -u github.com/aws/aws-sdk-go-v2/...)

Describe the bug

Issue: When we make call to DescribeVpcEndpoints it returns this State field with value in all characters lower case (available) contrary to what the client State constant defines first character in upper case(Available).

Regression Issue

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

Expected Behavior

I expect DescribeVpcEndpoints returns the State field with enum using the same casing as defined in the State.
For example the string value for State should be like Failed and not like failed .

Current Behavior

DescribeVpcEndpoints returns the State field string value in all lower case like failed.

Reproduction Steps

Here is the sample code to reproduce the issue.
Replace with real vpcEndpointId .
if the result says Expected Success then there is no issue and if it returns Manipulated Success then this bug exists.

package main

import (
	"context"
	"fmt"
	"log"
	"strings"
	"github.com/aws/aws-sdk-go-v2/config"
	"github.com/aws/aws-sdk-go-v2/service/ec2"
	"github.com/aws/aws-sdk-go-v2/service/ec2/types"
)


func main() {
	ctx := context.TODO()
	cfg, err := config.LoadDefaultConfig(ctx)
	if err != nil {
		log.Fatal(err)
	}
	client := ec2.NewFromConfig(cfg)
	input := &ec2.DescribeVpcEndpointsInput{
		VpcEndpointIds: []string{"<vpc-endpoint-id>"},
	}
	vpcEndpointsOutput, err := client.DescribeVpcEndpoints(ctx, input)
	if err != nil {
		fmt.Println("failed", err)
	}
	state := vpcEndpointsOutput.VpcEndpoints[0].State
	fmt.Println(state)
	states := types.StatePending.Values()
	for _, s := range states {
		if strings.ToLower(string(s)) == strings.ToLower(string(state)) {
			fmt.Println("checking the correct value")
			fmt.Println(s)
			if s == types.StateAvailable {
				fmt.Println("Manipulated Success")
			}
		}
	}
	if state == types.StateAvailable {
		fmt.Println("Expected Success")
	}
}

Possible Solution

Not sure if this issue is related to deserialization of issue at the server and client values for State.

Hello @rajramo61

Thanks for reaching out.

I have reproduced and confirmed that this is an issue. This was also reported in the past and not yet fixed by the EC2 service team #2864 , and I am tracking internal ticket (#70319347). I will reach out to the service team once again to try and get them to fix it.

I'll be closing this issue in favor of tracking it in the original reported github issue

Thanks,
Bhavya

Thanks @bhavya2109sharma for the updates!
Not sure if it would be a good idea to close this ticket but I would leave it up to you.
With this ticket being closed, someone else might create a new ticket for the same issue as folks mostly check the open tickets. The original ticket is open with older version of sdk which most of the folks won't check.
