When using type CognitoJwtVerifierSingleUserPool, getting compile error: "Types have separate declarations of a private property 'jwksCache'"

[jpbelang]

Describe the bug I wanted to declare a type for a verifier like this:

import {CognitoJwtVerifier} from "aws-jwt-verify";
import {CognitoJwtVerifierSingleUserPool} from "aws-jwt-verify/cognito-verifier";

export type JWTConfig = {
    userPoolId: string,
    tokenUse: "access"|"id",
    clientId: string,
    graceSeconds?: number
}

const verifier: CognitoJwtVerifierSingleUserPool<JWTConfig> = CognitoJwtVerifier.create({
    userPoolId: "somepool",
    tokenUse: "id",
    clientId: "someclientid",
    graceSeconds: 10
})

But compilation returns an error:

src/verifier.ts:12:7 - error TS2322: Type 'CognitoJwtVerifierSingleUserPool<{ userPoolId: string; tokenUse: "id"; clientId: string; graceSeconds: number; }>' is not assignable to type 'CognitoJwtVerifierSingleUserPool<JWTConfig>'.
  Types have separate declarations of a private property 'jwksCache'.

12 const verifier: CognitoJwtVerifierSingleUserPool<JWTConfig> = CognitoJwtVerifier.create({
         ~~~~~~~~
Found 1 error.

Versions Which version of aws-jwt-verify are you using? 2.1.0

Which version of Node.js are you using? (Should be at least 14) 14.17.1

If using TypeScript, which version of TypeScript are you using? (Should be at least 4) Version 4.5.5

To Reproduce Just declaring a type seems to cause the problem. I have a repo for reproduction: https://github.com/jpbelang/aws-jwt-verify-check

I'm not an expert around this, but navigating through IntelliJ, CognitoJwtVerifier.create() seems to go in dist/cjs, where CognitoJwtVerifierSingleUserPool seems to come from dist/esm.

I can cheat by importing something that seems wrong: import {CognitoJwtVerifierSingleUserPool} from "aws-jwt-verify/dist/cjs/cognito-verifier";

As an aside, swc compiles the code correctly.

Thanks for taking the effort of reporting this issue and providing code to reproduce it!

Yeah that is weird and seems to be the issue, we'll dive in this.

For the time being, this works too:

import {
  CognitoJwtVerifierSingleUserPool,
  CognitoJwtVerifier,
} from "aws-jwt-verify/cognito-verifier";

Fixed in v2.1.1
