Hi,

I have a dataverse table that has Image data type column, in my canvas app I want to be able to download it. I have this method https://www.matthewdevaney.com/power-apps-download-file-from-dataverse-file-column/ but not successful as I am having AccessDenied error.

Does Power Apps or Power Automate have any other method to create a download link then push it back to the canvas app so user can download it using the Download() function?

TYIA!!

Hi @PPDEV

It is super super important to understand we cannot see your code, so we cannot tell you what is wrong.

Please share your code (not the link from someone else). Then walk us through your code, and show us the part that is failing and how you execute it.

Without seeing your code, it's not good to try to throw other things out when we do not know what's wrong with what you have.

Cheers!

Hi @Michael E. Gernaey,

Please see the code I'm currently using:
UpdateContext({locClientEnvURL: LookUp('Environment Variable Values', 'Schema Name' = "ps_ClientEnvironmentURL").Value}); Download($"{locClientEnvURL}/api/data/v9.2/ps_vehicledatabases({gloAsset.'Vehicle Database'})/ps_vehicleimage/$value" )

In this implementation, I’m referencing the Environment URL from the Power Platform Admin Center, the Dataverse table name, the item's GUID, and the logical name of the image column.

Initially, I encountered an HTTP 401 error, which I resolved by adding a Link control that says:

"Issue with 401 error? Click and sign in here."

This link redirects users to the Environment URL to prompt sign-in.

However, when the download is triggered, instead of retrieving the image file, it downloads a text file. I've attached the downloaded file for your reference.

Appreciate your help on this—thanks in advance!

You are using an image column not a file column as in your example. If it works as in the example provided it will probably just show as binary data,
