I have a data table as a gallery. I have added an attachment column to show the attachment and to make it clickable if needed to be viewed.
I got this error when I added the column as below

the Text property = ThisItem.'{Attachments}'
I have tried this formula but it didn't work it just gave me True
(!IsBlank(Parent.Error) && Parent.DisplayMode=DisplayMode.Edit).
Any idea
Thanks in advance
