fix(events-targets): AwsApi is still using Node 16 #27002

mrgrain · 2023-09-04T15:49:24Z

Migrate the aws-api-handler code to use SDKv3 and move it into custom-resource-handlers.
Updates the Construct config to use the new code and Node18.
To verify functionality, the existing integration test has been extended to include a new rule and target that can be asserted on.

Includes a config change to the custom-resource-handlers package to run test from TS.

Closes #26998

Approved with DNM because this seems like something others may want to give a peek as well.

I get that this handler is for triggering effects and doesn't return a value, but I still feel like there might be a sharp edge here wrt Uint8Array types. Someone could use this to trigger Kinesis today passing a string payload and that would break right? We just pass parameters as aws-events passes them I suppose, and I'm not even sure how we could place a marker or something for special case deserialization.

Let me double check this,. But I'm quite sure the default logging algorithm does work for every object without fail. Unlike JSON.stringify() which often throws for unknown data.

Checked this. It writes the payload as bytes into the log: {"0":123,"1":34,"2":101,"3":114,"4":114,"5":111,"6":114,"7":84,"8":121, ... but doesn't fail. It's not great, but I think it's okay. If we have a generic transformation helper for API responses, we can add this later.

As for input: The function is called from EvenBridge (and the API directly) which is JSON by definition. Any other invocations would be outside the expected usage pattern and transformation into a string would be the users responsibility.

I think Mitch' concern is the opposite?

If the SDKv2 API used to accept a string and pass it on, but SDKv3 API now accepts a Uint8Array for that same field (but not a string), existing use cases are now broken.

There's also nothing we can do about it, and it's not really possible to pass that Uint8Array properly from EventBridge, ever.

Ah I see. Yes you are right about this.

It would seem like the only way to do this properly is to know exactly what fields are marked as "blob"s in the API

Yes and that seems unreasonable for us to do.

That seems unreasonable, yes. But right now this is breaking certain use cases.

…ay (#27034) In #27002 we have migrated the AwsApi Construct to SDKv3. However some SDKv3 Commands expect a `Uint8Array` in places where SDKv2 previously would accept a `string`. This is a problem because handler input is passed directly into the SDK calls and the input can only contain JSON data types. To solves this, we keep a list of SDK actions and parameters that should be coerced to `Uint8Array`. ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license*
