'XXX' cannot be used as a JSX component.

[happyeric77]

I am coming across an issue that the following error is thrown when I import @pontem/aptos-wallet-adapter

Situation

All the React Function Component gets the following error

'XXX' cannot be used as a JSX component.
  Its return type 'ReactElement<any, string | JSXElementConstructor<any>> | null' is not a valid JSX element

Reproduction

1. Clone the repo
   git clone git@github.com:notifi-network/notifi-sdk-ts.git

2. Install @pontem/aptos-wallet-adapter to @notifi-network/notifi-react-example package

cd notifi-sdk-ts
npm install
npx lerna --scope=@notifi-network/notifi-react-example run install  @pontem/aptos-wallet-adapter

3. get into the packages/notifi-react-example/src/App.tsx and import @pontem/aptos-wallet-adapter

// ...
import  '@pontem/aptos-wallet-adapter'; 
// ...

The error below will be shown only by importing @pontem/aptos-wallet-adapter without doing anything

All the JSX components become showing the same error 'XXX' cannot be used as a JSX component.

Could anybody give me a hint on how to get it around
