@kristofzerbe you were using custom_tags wrongly. It was never intended to be used this way. Simply remove that line and it should work.

Custom tags are supposed to work with:

<media:description>👉 Sign up for my newsletter to stay up-to-date on my new course: https://codestackr.com Did you know that Bootstrap has its own icon library? Apparently, they released the first stable version, 1.0.0, last week. In this video, we'll look at how we can implement these with any of our projects even if we are not using Bootstrap. That's right! You can use these independent of Bootstrap. Bootstrap 5 is not required. Since these are MIT licensed and they are just SVGs, we can use them anywhere for FREE!

You are trying access:

<media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://kiko.io/images/social-media/Discoveries-23-UI-CSS.thumb.png" height="1200" width="630"/>

Which is not supported by customTags. It doesn't support this tag with an attribute. it only suports:

<media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" height="1200" width="630">https://kiko.io/images/social-media/Discoveries-23-UI-CSS.thumb.png</media:thumbnail>

@kristofzerbe Looks like this is achievable via the current version of the feed parser. Will try to implement this feature when I have time. I recently upgraded the feed parser library. It is breaking due to that. Since this is an uncommon use case, most people won't see any issues using the workflow.

[gautamkrishnar]

@kristofzerbe if possible can you please rebase the PR you opened here rbren/rss-parser#224 it would easier if we have the code in the rss feed parser upstream instead of this project.

[gautamkrishnar]

Closing this since this is not a common use case. Will take a look at this once rbren/rss-parser#224 is merged
