Hi Blake,
Have you tried synchronizing your app directory in the Mendix Modeler?
App > Synchronize App Directory (F4)
Ok…. got it fixed! Instead of following the instructions I made the following changes:
Changed “Mendix project path” from ./tests/TestProject to: “../../”
Changed from “Class Components” to “Functional Components”
Not sure which one fixed it. Maybe the path. Since ./tests does not exist?
Thanks for the other comments!
