Your image has cut off the important part of the error message.
Tip: Every time you open a notebook, you must run all of the cells starting from the top.
I recommend you use the “restart the kernel and clear all output” option, and the run all of the cells again.
@Pankaj_Tinwal I think you are getting this error because the get_llm_response function hasn’t been defined. In Exercise 5, you import the client in order to be able to define the get_llm_response function. There should be a section of the assignment starting with “def get_llm_response(prompt):” where the function is already provided and you only need to make two small changes (content and temperature), but I don’t see this section in your screenshot. It should be right after the line starting with “Fun Suggestion.” In general, you should not add or delete cells or change their order in the assignments. Once the function has been defined, you should be able to run the candy description (which is an optional cell, by the way, right at the end of the assignment). I hope this helps!
