Importing LangServeInputPreProcessor in react?

[marifsw]

Hi,
First of all, a big thanks to the devs for this amazing piece of software.
I am not a frontend developer, so I might be doing something wrong here but when I tried to import LangServeInputPreProcessor like this
import {LangServeInputPreProcessor} from '@nlux/langchain'
It gave an error.
I had to modify
node_modules/@nlux/langchain/langchain.d.ts
to add LangServeInputPreProcessor to the last line
export { type LangServeAdapterBuilder, type LangServeAdapterOptions, type LangServeEndpointType, type LangServeInputPreProcessor, createAdapter };
It solved my problem but I am not sure if it is the right way to go about it.
Is there any other way to import LangServeInputPreProcessor or does the nlux code needs to export it?
