Vercel is not recognizing my LangchainRouter

[Gabrielmtvp]

I should be able to hit my End Point "/chat" on Vercel.

Scenario

I deployed my python application on Vercel

Actual result

When I try to hit my End Point on Vercel Project it returns as "404 Not Found". It looks like Vercel is not mapping this End Point.

Expected result

When I hit my End Point I should receive a stream of text.

@Gabrielmtvp just to confirm, are you able to access the endpoint locally?

I have not tried deploying on vercel (which can be a good adition to deployment options for the docs), can you please provide a step-by-step process of how you tried to deploy your app on vercel?

[Gabrielmtvp]

@ajndkr Yes, if I run locally the API works fine.

Exactly, it would be very good for the documentation.

Vercel has an option where you can give permission to your repository and then they deploy automatically using your repository on Github. I used this option.

Other interest point is that I created another simple route using @app.get("/") method from FastAPI and that one Vercel mapped with succesfull.

@Gabrielmtvp can you please try again? I've recently released v0.8 which has some significant changes.
