When creating a canvas app from "Start with data " from "Common data services", you get a 3-screen app. However, without doing anything there are multiple error on the EditScreen that all looks like this:

Is there a short term solution on how to change the formula?
Is my opinion correct that there should be no errors in an app that's been created from a 3-screen standard template?

Friendly greets

Did you set up your connection to any required data sources for the app? If you did not, you will get errors. Once you create the data source connection, the errors should go away.

That was a very fast response

I created the app based on one entity from the CDS that contains about 14 records of data. Below you can see that data is present in the EditScreen but the formula MaxLength=DataSourceInfo(Acties; MaxLength; "cr2f6_actie") is invalid. However Acties is the name of the CDS Entity and cr2f6_actie is the name of the field. According to the PowerApps documentations this seems like a valid formula.
