error in npm package "@peaq-network/sdk": "^0.5.1"

[Maltstar]

Using sdk from peak-network after installing the sdk from npm @peaq-network/sdk

npm install @peaq-network/sdk

does not work.
The npm package concerned is

 @peaq-network/sdk": "^0.5.1" 

Either using

 import { Sdk } from "@peaq-network/sdk";

if package.json is configured with

type:"module",

or if not, using

require("@peaq-network/types/package.json"); // @peaq-network/types is a peer dependency. 
const sdk = require("@peaq-network/sdk")

Only importing the Sdk either way causes a compilation error in the npm module @peaq-network/types/ :

Error: Cannot find module '.../node_modules/@peaq-network/types/src/index.js'. Please verify that the package.json has a valid "main" entry
