I have started to get the following “Script Handler Failed” error when using the clipping service from Mail to OF3.
Error executing handler script for <ScriptHandler:0x600000471950 com.omnigroup.OmniFocus.ScriptHandler.Mail NSBundle </Applications/OmniFocus.app/Contents/PlugIns/BuiltInClippingHandlers.plugin> (not yet loaded)>: Unable to convert the string “message:%3CDB7C0EE8.email@example.com%3E” to a url. Make sure that the string is a valid URL, including quoting characters that aren't valid in URLs.
This is similar to other issues reported in these Forums but in those cases - at least the ones that I saw - it was related to MailTags. I have completely removed the MailSuite bundle (using AppCleaner & Uninstaller) so is is not that. And there is no reference to MT in the error - so this must clearly be an OF problem. This is a very recent problem
