Issue with QR Code in Generated PDF File

[Aaron_B]

Hellooo Amazing community.

I  am having some trouble with my pdf that was generated in a workflow.

I have a QR code column (image type) in my table which generates a QR code using the following Formula:

CONCATENATE(
    "https://barcode.tec-it.com/barcode.ashx?data=https%3A%2F%2Fwww.appsheet.com%2Ftemplate%2Fgettablefileurl%3FappName%3DNewApp-2369121%26tableName%3DMaster%26fileName%3DFiles%2F",
    [Staff ID],
    ".pdf&code=MobileQRCode&dpi=300&imagetype=Png&eclevel=L"
)

 In my app, the QR code URL is working as intended - see below:

However, when this QR code is generated in my PDF report (using workflow). The link is broken - see below:

Does anyone know the reason for this issue?
