I added a dropdown to mine app. The values an labels are generated by an API call.
As long as i don't select 'allow multi select' everything goes wel. The list loads and i can select 1 item.
But the user have to have the possibility to select multiple fields.
The moment i select multi select i got this error:
I found out it's the following parameter that causes the error:
But i tried to add a 'String' but then he says he need a 'List<String>'
When i add an empty 'List<String>' it says he needs a 'String' 🤷
Anyone has the same problem and have a solution already?
