Describe the bug

When trying to update a "finalized" DataExchange Revision to "de-finalized" the request succeeds but has no change on the revision. We can finalize the revision by setting the Finalized parameter to true but are unable to de-finalize by setting it to false

Regression Issue

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

Expected Behavior

UpdateRevision should be able to finalize and de-finalize a revision.

Current Behavior

UpdateRevision is able to finalize a revision when Finalized is set to true but when set to false the request succeeds but has no effect.

logs show that when Finalized is set to false the request is empty

true

{"Finalized":true}
SDK 2025/04/17 10:07:50 DEBUG Response
HTTP/2.0 200 OK

false

{}
SDK 2025/04/17 10:10:11 DEBUG Response
HTTP/2.0 200 OK

Reproduction Steps

given the following config using an already created revision. Setting Finalized to true works. When set to `false the request body is empty. Cloudtrail shows this request working with both values when done in the console.

func main() {
	ctx := context.Background()

	cfg, err := config.LoadDefaultConfig(ctx,
		config.WithRegion("us-west-2"),
		config.WithClientLogMode(aws.LogRequestWithBody|aws.LogResponse),
	)
	if err != nil {
		log.Fatalf("failed to load configuration, %v", err)
	}

	conn := dataexchange.NewFromConfig(cfg)

	input := dataexchange.UpdateRevisionInput{
		RevisionId: aws.String("revision-id"),
		DataSetId:  aws.String("data-set-id"),
		Finalized:  false,
	}

	_, err = conn.UpdateRevision(ctx, &input)
	if err != nil {
		log.Fatalf(err.Error())
	}
}
