# I get “Terminal screen is required” when saving.

The flow must have at least one **terminal** screen (with `terminal: true` and one with `success: true`). The builder normally does this for the last screen. If you see this after **Import from JSON**, the imported JSON may be invalid—fix the JSON or rebuild the flow in the builder.
