[cube-client-core] TypeError: cube is not a function

**Problem**

We have a typescript project which we import cube-client-core library.
We are trying to instantiate it as documented:

```javascript
import cube, { CubeApi } from '@cubejs-client/core';

const cubeApi = cube(token, {
apiUrl: `${process.env.CUBEJS_API_URL}/cubejs-api/v1`,
});
```
The project compiles fine with `tsc` command.
However, during runtime, when this code is called, we get the following error:

`
TypeError: cube is not a function
`

We are struggling with that as we cant figure it out.
Logging the `cube()` function with `JSON.stringnify` gives us something weird:

```json
{"DEFAULT_GRANULARITY":"day","GRANULARITIES":[{"title":"w/o grouping"},{"name":"second","title":"Second"},{"name":"minute","title":"Minute"},{"name":"hour","title":"Hour"},{"name":"day","title":"Day"},{"name":"week","title":"Week"},{"name":"month","title":"Month"},{"name":"quarter","title":"Quarter"},{"name":"year","title":"Year"}]}
```

It seems it is holding the entire module and the default export is not working properly.

This is our tsconfig file:

```
{
"extends": "@tsconfig/node-lts/tsconfig.json",
"compilerOptions": {
/* Visit https://aka.ms/tsconfig to read more about this file */

"rootDir": "./src",
"outDir": "./dist",
"sourceMap": true,
"moduleResolution": "nodenext",
},
}
```

We are pretty sure we are missing something on the tsconfig, but cant find out what it is...

Any help would be much appreciated.

Thank you!
