Flow to save picture from Power apps to Sharepoint don't work for picture > 150Ko

[Anonymous]

Hi,

I created a flow which save pictures uploaded from power apps to a sharepoint picture library.

The flow works but when I try it with picture > 150Ko the flow also works (succeeded) but the picture in my picture library is empty like this : 

This is my flow : 

So in my flow I convert the uploaded image in JSON format in PowerApps using JSON function

Then in my flow the picture is converted from JSON to JPG using OneDrive

Then I save it into my Picture Library

But when I try with a picture > 150Ko it don't work I have a blank image like you can see at the top 

Thanks !
