Error while running LLMCHAIN

prompt = ChatPromptTemplate.from_template(
“What is the best name to describe
a company that makes {product}?”
chain = LLMChain(llm=llm, prompt=prompt)
product = “Queen Size Sheet Set”

I’m getting the below error when i ran the above code. I have used my own api key and end point.
InvalidRequestError: Must provide an ‘engine’ or ‘deployment_id’ parameter to create a <class ‘openai.api_resources.chat_completion.ChatCompletion’>
