Hey @SrilalS, had a look and fixed a few small things, but yarn build in @langchain/community seems to be failing:

[SrilalS]

Thank you for checking it out and for the changes.
The library itself works fine in our codebase, but I noticed the tsconfig is different so this must be an issue with type rules.
in the last commit have made it to follow the rules set in it.

I can't build this repo locally first as it having an issue with Windows. I'll try with WSL.
