Design a meta-prompt framework for constructing sophisticated Langflow prompt chains. This framework should enable users to define complex, multi-step automated business processes using Langflow&#8217;s capabilities.  The meta-prompt should guide the user through specifying individual prompt steps, defining data inputs and outputs between steps, handling errors and exceptions, and visualizing the overall workflow.  The framework should be flexible enough to accommodate various use cases, such as data analysis, report generation, and customer service automation.  The output should be a structured JSON representation of the Langflow prompt chain, including all prompts, input/output variables, and error handling logic. Include examples demonstrating how to chain together prompts for a simple business task, such as generating a sales report from a database, and a more complex task, such as automating customer support ticket resolution.  The success of the generated Langflow prompt chain will be measured by its ability to execute flawlessly and produce accurate, desired results based on the provided input data.  The JSON output should adhere to a consistent schema for easy integration into Langflow and other systems. Consider incorporating mechanisms for iterative refinement and debugging of the generated prompt chains.
