@peegeebee If by workflow, you're referring to the default web search for Google Translate, the URL structure was changed by Google a couple of days ago.
If you update to the Alfred 4.3.2 pre-release (by going to the Update tab, choosing "pre-releases" from the dropdown menu at the bottom and updating), you'll see that this URL has already been updated to reflect Google's change
