The problem would be in the view that is rendering cart.html, not remove_cart_item.

Your url is defined as:

Your error message is showing:

This is telling you that you’re only supplying 1 argument when 2 are required.

Your template is identifying two variables for arguments as shown here:

Since only one argument is being supplied, this means that the other argument you’re trying to provide either doesn’t exist or is null.

You need to check the view that is rendering this template, and the model(s) and the instance(s) of those models that are being used to see if it’s correct.
