Hello, I am learning the workflow in Mendix Studio Pro 9.24.34. I downloaded the sample project Vendor Onboarding in Marketplace https://marketplace.mendix.com/link/component/208932 which requires Studio Pro 9.18.4 or higher. I imported the App package for a new project in Mendix Studio Pro. When I try to run the project, an error occurred, it says An unknown error while starting the server. The screenshot is shown below And I do not know how to solve it now. Can anyone with kindness help me?
