Can't define dropdown list source in VB - UiPath Apps

Hi all,

I seem to be stuck…
I created an app in App Studio(in Automation Cloud), chose VB as expression language(not legacy). I’m trying to add a dropdown containing a list of options.
The documentation states that for the list source ‘Valid data types include arrays of String, Integer…etc.’.
So i created an Array of String(Text) app variable and tried using that as List source and it doesn’t work.
The expression editor for List source has ‘ListSource(of T)/ Fetch’ as expected type, so i cannot simply use the array i created. Screenshot attached.

Any help is welcome and appreciated.
Thank you!

Same issue here. Cannot use static dropdown due to the issue.


Please use the VB expression function as below to define static value.

AppsDataSource.from(New List(Of String) From {“Value 1”, “Value 2”, “Value 3”})

Basically you need to assign value to app data source and create a new list of string as above.
