PDF viewer not reading from blob storage

Hello Everyone

 

I was wondering if someone can help me . I have a PDF file which is uploaded to the Blob storage.

I want to view the pdf using the PDF viewer control

Currently I cannot view it

Below is the code that I am using in the Document property

"https://slrtestzzzzzz.blob.core.windows.net" & "ABC.pdf" & "?sv=2019-02-02&st=2021-02-11T03%3ABC3D"

Thank you so much

The Power Apps PDF viewer can only display PDFs from anonymous access sources.  It has no provision for doing authenticaton.  Blob storage would normally be an authenticated location.  Did you set the Blob storage to be accessible anonymously?  If not you'll need to use Flow to generate a temporary copy of the file in memory and display it from there.  Here's a walkthrough that may help.

Hi @mpezzutti,

 

The PDF Viewer control has some limitations in that the endpoint for the PDF must not require authentication.

 

To get around this, you can add a Power Automate button flow to the PowerApp to retrieve the Blob content using the Get Blob Content action of the Azure Blob Storage connector.

 

The example below demonstrates a similar process to view a PDF from SharePoint, but the steps should be very similar.
