I've been struggling with this for a few days and can't figure it out. I have a Gallery on one screen connected to a SharePoint list and I want to use some of the fields from the selected Item to populate a new form for a different SharePoint list which is on a different screen.
If I don't select an Item in the gallery it will just populate the form with top Item and this will submit as expected. However, if I try to select another Item I get this "data source might be invalid" error. I can't work out what the issue is, I've tried publishing the App and recreating the New form but the issue persists.
I found a few similar issues online but none of them seem to address my problem.
Does anyone have any ideas?

Thanks for the response.
So first Gallery witrh button that changes screen to the one with the form:
If the top item here is left as selected then the form works.
The apply button brings us to the screen with the form:
The default for the input boxes on each field are something like:
and the button just has:
is that enough?
That's because the gallery filters contains an if function, I wouldn't have thought that would affect the submission of the form.
I don't think the list will ever contain more than 2000 items so it shouldn't be an issue.
