Convert Image to url

[Apps_Tracklink]

Hi, I’m having an issue following the instructions detailed here: Displaying Images and Documents | AppSheet Help Center

I want to have a column on my google sheet that shows the url of the images that I’m capturing on column F of my spreadsheet. My final goal is to display the images on a data studio dashboard, that’s why I need the url.

I’m using the following formula to try to get the url: CONCATENATE(“https://www.appsheet.com/template/gettablefileurl?appName=”, ENCODEURL(“merchApp-1517199”), “&tableName=”, ENCODEURL(“E ADICIONAL”), “&fileName=”, ENCODEURL(CONCATENATE(+F,[_ROWNUMBER])))

But when I click on the link on my spreadsheet I get: 404 - File or directory not found.

Can someone please give me a clue of what I’m missing?

I greatly appreciate any help!
