An error ocurred while executing microflow - when building an app in Mendix studio

Hello, I'm new here and I'm trying to do some of the tutorials in the academy. But when it's building the app in the browser (tried Chrome and Firefox) I get the error "An error ocurred while executing microflow" after a few minutes. Clicking OK results in the same pop-up appearing again. Does anybody have a suggestion what the problem may be?

Check your recently changed microflows. You've probably created a problem in one of them. If you use Studio Pro, you can have a look in the console what the error is.
