I've simplified the useChat configuration to use the api parameter directly instead of wrapping it in DefaultChatTransport. This is the standard pattern for the AI SDK and should resolve the "A.string is not a function" error that was occurring at the gateway level.
I've added comprehensive error handling with try-catch blocks to both API routes and moved the Zod schema definition inside the POST function to avoid potential module-level evaluation issues. The error logs will now show us exactly where the "A.string is not a function" error is occurring, which will help us pinpoint and fix the root cause.

I've updated both API routes to use single quotes throughout and match the AI SDK examples exactly. The chat route now uses the exact same structure as the example, and the component generation route follows the structured data example pattern with the schema defined at module level. This should resolve the "A.string is not a function" error by ensuring we're using the AI SDK exactly as intended in the official examples.
