Hello, i’m trying to implement the single factor auth using custom jwt but some wierd error happens. When i use the `node-sdk` with same code but the import from `node-sdk` seems to be working.

- SDK Version:

```auto
"@web3auth/single-factor-auth": "^5.1.0"

```

- Platform:  
React with Vite and TS.

- Browser Console Screenshots:

Hey @bogdanpurnavel

I have tested the latest SFA SDK in [this example](https://github.com/Web3Auth/web3auth-core-kit-examples/tree/main/single-factor-auth/sfa-react-example). Could you try using this example with your configs?

Hey @shahbaz ,

I’ve ran the example provided and it works perfectly, issue seems to be that i’m using Vite for bundling… i will mark this as resolved.
