prompt_template_cannot_respond = (
"You cannot respond to the user input: {product}\n"
"Ask the user to rerun by inputting the name of a product in order for you to make a company out of it.\n"
)

cannot_respond_chain = (
PromptTemplate.from_template(prompt_template_cannot_respond)
| llm
).with_types(input_type=Dict[str, str], output_type=str)

why is input_type = Dict[str, str] i.e. two str types ?

If I changed it to Dict[str], it will complain that "Too few parameters for typing.Dict; actual 1, expected 2"
