I’m having the same issue. I need to create an equity curve chart for my company’s website using data in google sheets. The URL given is not formatted for CSV when you publish a chart in the new google drive (nor is there an option to like in the previous google drive). I tried entering the URL with the extension proposed by the OP and that hasn’t worked either. The file name does not have any spaces either. I get the exact same error as the OP. Help with this issue would be greatly appreciated as this is tied to our critical path in developing the website. Thank you!
