The streaming runs always get stuck indefinitely

We’re using "langchain": "^0.3.27"` `“langsmith”: “^0.3.65” versions with JS + Cloudflare Workers and our streaming runs always get stuck in the loading state, and we can’t see the response, which makes having langsmith useless. This doesn’t happen for non-streaming, though.

Sometimes, some of them load, but it’s unpredictable. The majority of them never resolve.
This doesn’t affect the actual LLM response, but I can’t see the response, so I can’t investigate issues.

could you give us a little more info on how you’re tracing? some sample code would help
