The response rendering freezes midway and throws an error in production mode

[r0x07k]

I often observe strange behavior in production mode. The LLM response renders unevenly and eventually freezes midway with an unspecified error. There is nothing in the JS console or stdout. When I switched back to development mode, the issue stopped occurring.

Unfortunately, it's intermittent, and I haven't been able to reliably reproduce it so far.

It seems that the problem lies in the handleSubmitProduction function. I would prefer to use it instead of the one supplied by the useChat hook, but for some reason, it's unstable.

By the way, what is the reason for code duplication in page.tsx and [id]/page.tsx?
