Get "Errors in tools" in "Asking about Code.ipynb"

I have uploaded this https://raw.githubusercontent.com/AnswerDotAI/solveit_demos/refs/heads/main/Asking%20about%20Code.ipynb to https://solve.it.com/
Then, I send a prompt at the bottom but get strange message:

```
Errors in tools:

- `How` not found. Did you run it?

- `does` not found. Did you run it?

- `Can` not found. Did you run it?

- `how` not found. Did you run it?

- `message` not found. Did you run it?

- `a` not found. Did you run it?

```

If I move the prompt to here, it works fine:

And, if I change to `## How add_msg() Works` , it also works fine:

Start with Asking about Code.ipynb from the linked repository and reproduce the error on solve.it.com using the prompt locations shown. Compare the failing prompt location with the working location and the “## How add_msg() Works” heading; done means the original prompt no longer produces the listed “Errors in tools” messages.
