onFinish strange error with Drizzle/BASE_URL: "values() must be called with at least one value"

[fullstackwebdev]

Using the repo's onFinished I am getting an error, but only when tool calling. Is there a way to get better tracing or debugging for resolving this? All this abstraction seems to be confusing, what is the actual error?

I have the same problem, and I don't know how to debug it, the document didn't clarify anything, not even returning a message like greeting in the tool call.

If you add new tool calls, ensure that you include them in both the AllowedTools type and the allTools array in /api/chat/route.ts. Failing to do so will result in incomplete messages being passed to onFinish when the tool is invoked, causing the aforementioned error.

That's the correct answer, the document missing this step.
