 ### Fixed
 - Fixed a caching bug where the Fields service could still think a field existed after it had been deleted. ([#2985](https://github.com/craftcms/cms/issues/2985))
+- Fixed a PHP error that could occur when saving entries with a URI format that contained certain Twig filters. ([#2995](https://github.com/craftcms/cms/issues/2995))
