Error while fetching podcasts, but urls are found

I've set up this great tool on my NAS and it worked great, but now I'm getting this error (debug=true):

I've tried both Zenrows and ScraperAPI, but that doesn't work either. While it gives an error, it can found the (correct) mp3-urls. Any idea how I can fix this?
