Client-Side Function Calls Not Invoked

================================================================================================================================================================

Issue

---

I upgraded the AI SDK to v3.0.20 or newer. I am using OpenAIStream . Client-side function calls are no longer invoked.

Solution

---

You will need to add a stub for experimental_onFunctionCall to OpenAIStream to enable the correct forwarding of the function calls to the client.

const stream = OpenAIStream(response, {  async experimental_onFunctionCall() {    return;  },});
