# What is “terminal screen is required”?

Meta requires that the flow has at least one **terminal** screen (the end of the flow). The builder normally ensures this by marking the last screen as terminal. If you see this error (e.g. after importing custom JSON), fix the JSON so that the last screen has `terminal: true` and `success: true`, or use the builder to create the flow.
