This issue might go away when we decouple entity content and the api more, but the issue can still occur with new entities. A solution should be found.
EditEntity uses RequestContext::getMain() in case of a new entity. If entity is created via a special page, then special page is the title. If entity is created via the api, then Title (including $wgTitle, which request context uses as fallback) is null and has potential to cause issues.
Catchable fatal error: Argument 1 passed to Wikibase\EntityContent::getParserOutput() must be an instance of Title, null given, called in /Library/WebServer/Documents/php-master/extensions/SpamBlacklist/SpamBlacklistHooks.php on line 28 and defined in /Library/WebServer/Documents/php-master/extensions/Wikibase/repo/includes/content/EntityContent.php on line 142
