File not found after generate a PDF

Hello everyone ,

So I am making an Inventory Management app that can generate PDF report using automation

I have check that the app was succesfully generate a PDF file in my google Drive

My gsheet are in /My Drive/

but when I press the open file action button it show this

These are my setting in appsheet

As per your definitions and if you have not changed the defaut app folder, the PDF file is probably saved to Drive > appsheet > data > Appname-1234567 > Files.

When using a file column, you need to write the file name with a correct path starting from the folder where the gSheet is. You said it’s in the Root, then your formula shoule be something like “/appsheet/data/AppName-1234567/Files/”&[Item Name]&“.pdf”

I already change the default folder to /appsheet and the pdf generate on here

Then you should use “/appsheet/Files/”&[Item Name]&“.pdf”
