Passing Category object into function results in error

I have an assignment where I create objects that need to communicate with each other. One of the requirements is to create a function named create_spend_chart which will display a chart with based on values within the object.

The problem is that when calling the function with a list of categories, I’m receiving an error. When I run this on my home computer, it works as expected and passing in multiple objects is crucial to not having to perform a lot of rework on my code. Is there any advice anyone can give on what is going on with with the freeCodeCamp environment is recognizing the list value as a list object rather than a Category object?

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

Have you tried to print out the args in the create_spend_chart function? This would clear a bit why exactly the error is happening.

Bottom line is - one of these is not the expected way to call the function as it is currently defined:

create_spend_chart([food, gasoline, entertainment])
create_spend_chart(food, gasoline, entertainment)
