Hi @venky232

I've just built this out myself. You don't need to prepend the URL - or at least I don't.

I simply used First(ThisItem.Attachments).AbsoluteUri and it worked fine for me.

Hi @venky232

Apologies. I have uploaded a PDF and tried the following:

This is my expression:

Hello venky232,

have you resolved this problem? I'm having the same problem like yours. With this Uri function, both of the image and pdf thumbnail are not showing. I have no idea why. Only using the First(ThisItem.Attachments).Value is fine for me without the uri in front of &.

Hi
I'm experiencing the same issue. On Friday after several attempts everything was working, but now on Monday it has reverting to showing the following instead of the attachment thumbnail.
I am using -
"https://site.sharepoint.com/_layouts/15/getpreview.ashx?path="&First(ThisItem.Attachments).AbsoluteUri & "&Resolution = 6"

All help appreciated
