kbennett I think you are missing the component convert to CSV between steps 3 and 4. Since the output of your component from step 3 is a dataset as listed in the file names above you will have to use convert to CSV module to convert the dataset to a CSV. This ensures the CSV output of this module is used as input to the export data module and the correct CSV file is available in your container.
In the current setup the export data module takes the output of the input module and tried to export the same, if you click on the module above export data and view the job details the same would be available in the Outputs + Logs tab.
