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"

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!!
