In the default I would put a log message to the actual value you are basing the switch on. It could be something as simple as a space at the end of an erroneous capitalization.
As an additional tip, the switch cases don’t require quotations if they are string type.
Yeah, I know exactly what you mean. It seems to be the only activity from UiPath that doesn’t require quotations, perhaps because you already have to set the type within the switch activity
