It looks like ftrack changed requirements for creation of custom attributes and "config" must be always filled. This issue also discovered that the error was not handled and shown/reported to user at all, so reporting from the action was enhanced.
Testing notes
Remove some custom attributes from ftrack if all are already created (should be attribute without config, e.g. boolean).
