Error: Call to undefined method Drupal\Core\File\FileSystem::uriScheme()

Here is a link to another issue where there is a patch that addresses this issue as well as another issue you may have if you attempt to upload files vs. providing a file path. https://www.drupal.org/project/paragraphs_browser/issues/3355760#comment... 🐛 Error: Call to a member function getFileUri() on array in paragraphs_browser_paragraph_type_form_builder() RTBC

OK, I guess we should mark this as a duplicate of that one. I've given credit to stefvanlooveren over there since this issue predates that one.

Is this still an issue since 8.x-1.30?
