Hi Aleyna,
In order for this to work you need to add a file entity to the create document action.
Hope this works for you
Now I have to insert the document template, but was this template created in the tutorial or is it created by us? A blank page comes to me and when I insert a data view, no lines are filled anyway. I do not know how to proceed and it is not described in detail in the tutorial, I do not understand it.
In the first picture is the example from the tutorial and in the second the one how it looks for me, I hope I could explain it.
