Hi Sayn,
I received your page URL and there seems to be no obvious errors.
Running the above command should not return any error.
It should display a result like in the below image.

Probably, the code you have entered is incorrect or has a mistake.
Can you please run the command again like in the screenshot above and share me a “screenshot”?
Please upload it to a iamge hosting service like https://imgur.com/
Thanks,
Aakash
