Hi 👋, I'm using typescript and having trouble understanding how imports are meant to be handled during function serialisation. We are using:

const { isLeft } = await import("fp-ts/lib/Either");

Which is `tsc`'d into:

const { isLeft } = await Promise.resolve().then(() => __importStar(require("fp-ts/lib/Either")));

Where

__importStar

is defined at the top most level of the file. After function serialisation, it appears that the

__importStar

definition is not retained (i.e. it hasn't been captured?) so the lambda fails during invocation. When I switch

importHelpers

on in

tsconfig.json

, it does work. The tsconfig.json from the aws-typescript template doesn't have this set. So... can anyone shed light on the expected way to import those runtime dependencies?

I dont really know your specific problem but the import

const { isLeft } = await import("fp-ts/lib/Either");

in ts would be

import { isLeft } from 'fp-ts/lib/Either'

assuming the library supports ts
