I am creating a content scraping project. The workflow Master Scenario: retrieve urls from Airtable and analyze whether the urls are complex or simple to scrape. Subscenario 1: scrape the simple urls Subscenario 2: scrape the complex urls. In the Master Scenario, after formatting the output as json, I have added Call a Subscenario module and from what I see the output is fine. I have set up the Scenario input & outputs with the input fields in the Subscenario 1 (haven’t got to the 2nd one yet) and have started the scenario with an Iterator. Challenge: no matter what I do, the data doesn’t seem to be transferred to the Iterator. I have tried various ways, the posts and even Make’s AI Assistant, but no luck. Here are 5 screenshots Master – Call a Subscenario Setting Master – Call a Subscenario Output ![Subscenario - Iterator Output](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/1/6/16752775c7883fa132b708e1f7cce4e35f8ce6b9.png) ![Subscenario - Iterator Settings](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/8/f/8f49aac05a62f622c7cd207314e75fd1e1da25c8.png) ![Subscenario Scenario Inputs & Outputs Settings](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/7/8/78dac0727104bf6f19fa14fffb3f73a79b5fb469.png) ![Master - Call a Subscenario Output](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/d/f/dfc4ee7c8c4036dae2855fe929b27d26848891ef.png) ![Master - Call a Subscenario Setting](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/6/4/643d3256319f21b1226e0f0907d39b1405278257.png) Subscenario – Scenario Inputs & Outputs Settings Subscenario – Iterator Setting Subscenario – Iterator Output What am I doing wrong?

Hey, can you please also share with us how does the `28. Choices[] Message.Content` look like? I’m guessing it’s a plain text JSON object? If so, you should be using the input type Dynamic Collection - this input type implicitly parses a JSON string into a Collection that you can work with in the subscenario. Also, if you start your subscenario with the Start a Subscenario module you’ll see the parsed input values that you can easily map in subsequent modules. Alternatively, you can add JSON parse JSON module before the Call a subscenario module that would output the parsed JSON object and to the call module, you’d only map the actual property that contains the array of URLs ---
