 ### Fixed
 
+- Fixed `BaseView.on_timeout` and `Paginator.on_timeout` behavior: views no longer raise
+  unnecessary errors on timeout.
+  ([#3019](https://github.com/Pycord-Development/pycord/pull/3019))
 - Fixed `RawMessageUpdateEvent.cached_message` being always `None` even when the message
   was cached. ([#3038](https://github.com/Pycord-Development/pycord/pull/3038))
 - Fixed downloading animated emojis which were originally uploaded as WebP files by

discord/ext/pages/pagination.py
