It seems that there's no specific information in the seized files about the issue you're encountering with fields like "HTTP method" and "URL" getting empty when duplicating or remixing a flow in BuildShip. This might be a recent change or bug that has not been documented in the available files.
For such issues, it's recommended to contact BuildShip support directly through in-app support or their official support channels, as they may be able to provide real-time assistance and investigate the issue further. Let me know if there is anything else I can help with!
