Hi I know taht this issue was raised multiple time but I still not find a clear answer to this issue:
I'm trying to pass the URL of a document created into sharepoint to power app :

it's working fine into flow and retrun the url I want :

and then I set a button in power app with : UpdateContext({datafromflow:Bonpdf.Run()});;
However, the variable "datafromflow" always return a true/false!!
what I'm doing wrong?
