Can't download PDFs today - "Couldn't download - No file"

Posted on by RacRig5407

Canvas app on GCC High -- I have text fields inside a Container (not vertical or horizontal - just container) and the experimental PDF function is turned on. The PDF is being generated fine and I can see it in a PDF Viewer control. The problem is the downloading of the file. I'm using the same exact method (from Reza Dorani) that is working fine in a different app of mine. But here, it's not working. When I click the file name in an Attachment control, the Downloads dialog says "Couldn't download - No file"

cant download pdf.jpg

The varPDFBlob is being created (apparently successfully) on a button click:

Set(
 varPDFBlob,
 PDF(
 conDashboard,
 {
 Orientation: PaperOrientation.Portrait,
 Size: PaperSize.A4,
 Margin: "24pt 24pt 24pt 24pt",
 ExpandContainers: true
 }
 )
)

And the Items property of the Attachment control is set to:

{Name: "test"&".pdf", Value: varPDFBlob}

Can't get the file to download successfully. Any ideas? Thanks to all!!

Well this seems to have worked for me! The Name and Value were already in place, but I re-selected the values into the fields and tried again. Got a file today -- so it was either this setting or something else got refreshed and cleaned up magically overnight.

Did you try re-selecting the values into those fields? I don't know why but it's working for me today and that's all I did.

This error continues to come up intermittently. I find that the Value field keeps changing back to "Name" and I have to correct it over and over. But even after correcting the Name and Value fields, the PDF will not download. It works fine one minute, then it fails and I can't figure out what changed. There must be some kind of bug here.
