I started to build new Power App. SharePoint list form works perfectly but I using also LOOKUP data from existing SharePoint list (about 400 lines). Unfortunately SharePoint list form works only as "dropdown" without option to search.
So I created customized form via Power Apps with combo box which is able to search. Unfortunately If I publish the form created in Power Apps I'm not able to create new item. Also I'm not able to edit existing fields as I getting still same error "An entry is required or has an invalid value".
I tried several hints from this forum.
1) Tittle column is not required.
2) I tried all fields setup as not required in SharePoint list. Then I setup all fields as no required in Power Apps - doesn't help.
3) I tried in app advanced settings turn off delayed loading
I don't have any idea how to fix it.....if I switch back to SharePoint list everything works pretty well.
Solved! Go to Solution.
Please change the property to "Title"
It is a string, so do not forget the quotes around it.
