Streamable object crashes on client side after 2s of streaming in production only

Description

Check out this sample project, and click on the RAG example: https://github.com/BoundaryML/baml-examples/tree/main/nextjs-starter . Locally it works completely fine, but after deploying to vercel, clicking on the "answer question" button to start streaming will crash with a client-side error after 2 secs of streaming, saying that it can't construct a URL.

All you need is an OPENAI_API_KEY to test.

Code example

No response

Additional context

No response

tried with 14.2.0, and now with nextjs15, same crash.

I found the issue -- when rendering a Link with a partial string response (while it's streaming), the url is invalid. I now only render links when the stream is complete.

Although super weird i only saw this in production.
