 Why? Because we cannot define a function in the same way as `chat-post` was created. We need to change it to `postChat` without the hyphen. Additionally, we need to modify the handler of the `chat-post` function to `postChat` and also, specify that this function will be a `POST` instead of a `GET` function.
