Hi everyone,
I have a canvas app that uses a LookUp formula to display images from a SharePoint list's Image column. The formula is straightforward:
LookUp(MyList, ID = DropdownControl.Selected.Value).ImageColumn.Full
This was working perfectly in both the editor and the published app. Recently, without any changes to the app, the data source, or the SharePoint list, images stopped rendering entirely — both in the Studio editor and in the published version.
What I've confirmed:
- The images exist and display correctly in the SharePoint list itself
- No formulas, connections, or permissions were modified
- Previous versions of the app (which used the same formula) were working fine
- The issue affects both edit mode and published mode
Environment:
- Canvas App connected to SharePoint Online
- Image column type in SharePoint list
- Using LookUp to retrieve the image
Has anyone else experienced this recently? Based on forum research, this appears to be a recurring platform-side issue, but I'd appreciate any confirmed workarounds.
Thanks in advance.
