Decoding failure

[Buratti]

Describe the bug Lambda.UpdateFunctionConfiguration fails when it comes to decode the response. The function configuration is updated correctly.

dataCorrupted(Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "LastUpdateStatusReasonCode", intValue: nil)], debugDescription: "Cannot initialize LastUpdateStatusReasonCode from invalid String value Creating", underlyingError: nil))

To Reproduce Steps to reproduce the behavior:

let httpClient = HTTPClient(eventLoopGroupProvider: .singleton)
let awsClient = AWSClient(httpClientProvider: .createNew)

defer {
    try? awsClient.syncShutdown()
    try? httpClient.syncShutdown()
}

let lambda = Lambda(client: awsClient)
let request = Lambda.UpdateFunctionConfigurationRequest(functionName: "")
_ = try await lambda.updateFunctionConfiguration(request)

Expected behavior Should not fail

Setup (please complete the following information):

• Version of soto: 6.8.0
• Authentication mechanism: profile

Additional context Tested in eu-central-1, should not be relevant though.

@Buratti are you able to breakpoint inside the HTTPClient call and get the JSON body returned? Because Creating should not be being returned as the reason code - https://docs.aws.amazon.com/lambda/latest/api/API_UpdateFunctionConfiguration.html#lambda-UpdateFunctionConfiguration-response-LastUpdateStatusReasonCode

[Buratti]

Sure! I'll need an hour though, I'm OOO right now. What I can tell you right now is that the I have tried the same invocation using aws-cli earlier, and it also returned Creating. I'll paste the response received inside the HTTPClient in a new comment later!

@Buratti would you be able to try this with the 7.0.0-rc version

Actually don't bother Creating as a case doesn't exist in 7 either. I may have to patch the enums

[Buratti]

Breakpointing here the response does indeed return a "Creating" string.

This looks like a bug on AWS side, I couldn't find any reference of Creating either and GetFunctionConfiguration does not even return it. Creating also looks like an unexpected case for a function that has been "created" and updated for over two years.

It is a pain when the model files amazon provide are not up to date with the actual reality. I have add a patch to code generator and have run it on the models. You can test the aws-update-models branch, but that'll require you to upgrade to 7.0 code base. As long as you are only using Swift concurrency that shouldn't be too hard.

I'm hoping to do v7 release in the very near future

Looks like they've just updated them (it's in #717)

Looks like they've just updated them (it's in #717)

That's my patch

[0xTim]

Oh lol I misread the PR 😅

[Buratti]

IMHO I would argue that this is a bug, not a "synchronization" problem with their models. Otherwise I couldn't understand why the difference behavior between GetFunctionConfiguration and UpdateFunctionConfiguration. I've open a case on AWS Support and update this issue with their answer.

This isn't a big issue for us right now, it's a very simple helper script and I can work around it ignoring the DecodingError, not a big deal.

I will try the patch, migrating to soto 7 was very high on my priority list anyway (thanks for adding tracing support, loved seeing it).

You are probably correct, but AWS aren't always fast to move so I tend to patch models until they are fixed.

Please keep us updated on their response thanks
