Doubt in final project

Hello all, I’ve almost completed my final project but I have some doubts. My project will display all the projects completed by me so far for the certification exam, you could even download it from Dropbox server. The issue I’m facing is when I run the scenario in Integromat and test it from Voiceflow by sending an API request, the flow in Integromat goes only until the first Dropbox module. Kindly refer the attached screenshots and help me solve the issue.
