Has anyone implemented Cognito confirmForgotPassword (or maybe it’s in connect and I’m just looking in the wrong place?)

[dave]

It's not in connect but we do accept PRs... 🙂 https://github.com/http4k/http4k-connect/tree/master/amazon/cognito

[dave]

remember to add it to the Fake 😉

[dave]

And you'll also probably need to do ForgotPassword as well ..

[dmcg]

ForgotPassword is already there, which is why I thought there was a chance that I’d just missed the confirm

[dmcg]

So… I’m getting a response from AWS saying {"__type":"SerializationException","Message":"Start of structure or map found where not expected."}
I assume that this is something to do with JSON adaptor bullshit and @JsonSerializable - I suppose that I can’t actually add extensions in my own codebase without using moshi/kotshi/bishBashBoshi?

[dave]

Stick a debug on and look at the payload?

[dmcg]

My assumption is that I haven’t generated any JSON mappings for my class unless I add the annotations and run some build step?

[dmcg]

We’re using Jackson, I wondered if there is any way I could get a local (to our codebase) extension to use our Json not moshi?

[dave]

what does your action look like?

[dave]

wait a minute - ForgotPassword isn't supported by connect?

[dmcg]

Hmm. You don’t have ForgotPassword, but you do have AdminResetUserPassword, which we are using

[dmcg]

That sends a confirmation code

[dave]

@Http4kConnectAction
@JsonSerializable
data class SomeAction(
    val ClientMetadata: Map<String, String> = emptyMap()
) : CognitoAction<Unit>(Unit::class, Jackson) {
    override fun toResult(response: Response) = with(response) {
        when {
            status.successful -> Success(Unit)
            else -> Failure(asRemoteFailure(this))
        }
    }
}

[dmcg]

Which I’m trying to submit with

@Http4kConnectAction
data class ConfirmForgotPassword(
    val ClientId: ClientId,
    val Username: Username,
    val ConfirmationCode: ConfirmationCode,
    val Password: Password,
    val ClientMetadata: Map<String, String> = emptyMap(),
    val AnalyticsMetadata: AnalyticsMetadata? = null,
    val UserContextData: UserContextData? = null
) : CognitoAction<Unit>(Unit::class) {
    override fun toResult(response: Response) = with(response) {
        when {
            status.successful -> Success(Unit)
            else -> Failure(asRemoteFailure(this))
        }
    }

[dave]

you can override the automarshalling to use Jackson

[dave]

aren't we nice allowing you to do that? 😉

[dave]

: CognitoAction<Unit>(Unit::class, Jackson)

[dmcg]

Aha - autoMarshalling: AutoMarshalling = CognitoMoshi
You are, I think it’s safe to say, the most nicest http library

[dave]

we are like - THE most considerate library authors on the planet.

[dave]

I do hope you're going to contribute that back? you could even make a video about it

[dave]

(not an onlyfans video - the other one)

Leaving some breadcrumbs for the next person to come this way - Jackson by sends properties with lowerFirstLetter even when the data class has eg val Username: Username So I’ve had to use

@JsonNaming(PropertyNamingStrategies.UpperCamelCaseStrategy::class)
@Http4kConnectAction
data class ConfirmForgotPassword(
    val ClientId: ClientId,
    val Username: Username,
    val ConfirmationCode: ConfirmationCode,
    val Password: Password,
    val ClientMetadata: Map<String, String> = emptyMap(),
    val AnalyticsMetadata: AnalyticsMetadata? = null,
    val UserContextData: UserContextData? = null
) : CognitoAction<Unit>(Unit::class, autoMarshalling = CognitoJackson)

[dave]

Yes - this is one of the reasons we don't use jackson..

[Andrew O'Hara]

🤔 are you overriding connect to use jackson simply to avoid duplicate marshallers in your classpath?

[dmcg]

No, I’m trying to get another action running in my codebase without having to use moshi

[dmcg]

just for that one, until I make a PR and have it built with moshi for me

[dmcg]

OK, looks like I have that working. I’ll think about what the fake could reasonable do and submit a PR

[dmcg]

Thanks for the help. I take back everything I said about you

[dave]

even the bad things?

[dmcg]

I’ve said things that weren’t bad?
