Hi Byron — which version of awsx are you using (eg in package.json)?

NewPulumi

Ok yeah. This API (`awsx.apigateway.API`) is from a previous (pre-1.0) version of AWSx — for example here, which is using that API (via ^0.40.0): <https://github.com/pulumi/examples/blob/e2e5eb426dbf5b57c50bba0f8eb54fe982ceddb1/aws-ts-apigateway/index.ts#L18>

You probably want the `@pulumi/aws-apigateway` package: <https://github.com/pulumi/templates/blob/master/serverless-aws-typescript/index.ts#L16>

<https://www.pulumi.com/registry/packages/aws-apigateway/>

However, this is not for awsx, is for aws, but, as you were saying, if i downgrade the version of @pulumi/awsx to one lower than 1.0, Should it work?

Actually, perhaps an alternative: I believe if you change that reference to `awsx.classic.apigateway.API`, that might work for you?

I haven’t spent much time with the 1.0 package yet, but it looks like `classic` may bring forward the APIs that were there pre-1.0

(Ideally you wouldn’t downgrade, because you’d essentially be stuck in a pre-1.0 world.)

This is probably the way to go if you’d prefer not install aws-apigateway.

```error: Error serializing '(event) =&gt; __awaiter(void 0, void 0, ...': index.ts(35,26)```

That I haven’t seen — looks maybe related to the code you’re attempting to serialize (for example as your Lambda event handler)?
