Steps to reproduce the issue

Tested in Joomla 4 @ dea8aa6

Create a new site module of type "Feed Display"

I used http://feeds.bbci.co.uk/news/world/rss.xml for my feed link

load the frontend of the site to view the feed

(Set error reporting to maximum in global config to get stack trace)

Expected result

Feed loads

Actual result

Object of class Joomla\CMS\Feed\FeedLink could not be converted to string

(I love seeing the Symfony error pages in Joomla ?)

System information (as much as possible)
