Printing via printnode: File not found

[mukhammadrasul]

I want to print reciepts automatically via printnode. My app is creating pdf files and sending requests to the printnode successfully but it can't print it. I found the problem. When I try to open the link in the content, it isn't downloading or opening pdf document so in my opinion, printnode didn't know what to print.<URL removed by staff?

This screenshot shows everything in the Print to Cloud task in the automation. Please help me to resolve this issue?
