When the 'Remote RSS feeds' block is enabled and added to a Moodle block, the following error message appears when trying to access the course:

This error occurs in all our 4.2 Moodle instances and seems to be intermittent (sometimes the error pops up, sometimes it doesn't). 

I have found the same error reported on the issue section of the SimplePie GitHub repo:

BUG must be of type string, bool given in /framework/simplepie/src/Locator.php:330

A fix was later submitted for this issue and merged into their master branch on March 19th 2023:

Locator: Fix type error when no extension

However, the SimplePie library within Moodle core was last updated 6 months ago (commit: MDL-76909 Libraries: Upgrade Simplepie to 1.8.0) and does not include the fix for this issue.

I was wondering if this library could be updated so that this error will be fixed?
