🟡 Issues with BAML Playground requests using Lite...

12/23/2025, 1:15 PMI’m using LiteLLM as a router with BAML, but the BAML Playground won’t send requests. It fails with:
“Unspecified error code: 2 error sending requests. If you haven't yet, try enabling the proxy.”
I enabled the proxy, and both curl and a Python script calling the same function work fine. I’ve set the LiteLLM key in both the Playground UI and my environment variables. Why would requests succeed via curl/Python but fail only in the Playground, and what should I check to fix it?

12/23/2025, 2:36 PMah! remote ssh doesnt work for the playground yet 🙁 cause the proxy points to localhost:XXXX, which is likely not working

12/23/2025, 2:36 PMthe reason without the proxy doesn't work is because litellm likely enables CORS in its servers

12/23/2025, 2:43 PMCan BAML Playground support URLs that are IP addresses? Because even in a remote SSH environment, when I previously accessed Gemini or DeepSeek, I didn't need to enable a proxy, and the tests ran successfully

12/23/2025, 2:44 PMyep! those should work when proxy is disabled (as long as there's no CORS restrictions)

12/23/2025, 2:44 PMthe proxy is really only for CORS reasons

12/23/2025, 2:45 PMBut in this environment, this error will still be reported

12/23/2025, 2:45 PMan easy way to confirm is to open the developer console in vscode and look at the network tab!

12/23/2025, 2:49 PMIt does appear to be a CORS issue

Vaibhav (BAML 🐑)
12/23/2025, 2:49 PMyep! the server you're pinging has CORS enabled, likely you nseed to check how to disable CORS for it!

12/23/2025, 2:50 PM(our proxy solves that issue, but in SSH environments we cant 🙁 )

12/23/2025, 2:51 PMOkay, no problem, as long as I know the reason. I'll have the team use their local machines for testing👍
