Could you please share more details about the formula you typed within the Items property of the Attachments control?
Actually, the Attachments field of a SP list item is required to provide a Table value consists of Attachment type data. The standard data structure of Attachment type data as below:
DisplayName: "File Name",
Value: "File Content",
So if you want to provide a Collection of images (or files) within the Items property of the Attachments control, your Collection data must have the following data structure:
I have made a test on my side, please take a try with the following workaround:
Add a Add Picture control and a button within your Edit/New screen (as above screenshot, on your side, it is FormScreen1), set the OnSelect property of the "Add" button to following:
Unlock the Attachments Data card, set the Items property of the Attachments control to following:
Add the following formula within the OnSuccess property of the Edit form:

Hi @v-xida-msft, thanks a lot for your answer. But it didn't work as expected.
Here is my formula:
'Teste_Gestão de Relacionamento';
'Qual é a sua Coodernação':[@Dropdown4].Selected.Value;
'Pauta da reunião':[@TextInput1].Text;
'Qual a data do Engajamento':[@DatePicker2].SelectedDate;
'Funcionários Anglo American Presentes':[@Label2].Text;
'Avaliação Geral da Reunião':[@Slider2_1].Value;
In the Attachment "AppSample_2" there are my Sharepoint list columns. In "AppSample_3" the details of the formula problem. In "AppSample_4" I have my full formula and one of my app screens, as you can see as I use multiple sharepoint list connections I use a custom app, not a prebuilt form.
Every time I try to upload Attachments through the formula I get this error of incompatibility. Hope this makes my problem more clear.
Again, thanks a lot for your help.
