Script integration/output error

Hiya,
I would like to run this script in air table. It takes Soundcloud URLs and searches for the most hi res image artwork available and then give back the image url. I would like to run this in airtable with one column being the source urls and with another other being the assocaited output image urls.
Can anyone offer any guidance aboiut how to integrate this?
Script here:

Cheers,
