Hi,
I'm trying to trigger a URL as a GET HTTP request from a button with the Launch function, but it doesn't seem to be working: while the web page opens, the flow connected to the HTTP requests are not triggered.
However, if I manually click on the URL itself, the actions are correctly triggered. Any idea of why that happens?
Here's a screenshot of my screen and my code for reference:

OnChange property for Dropdown2:
//Set variable to current selection
Set(varSelectedBatch2, Dropdown2.SelectedText)
OnSelect property of the button:
Set(
varFirstPartURL,
"https://prod-90.westus.logic.azure.com/workflows/afa4450c027141ffa05db3dca4f637ed/triggers/manual/paths/invoke/batch/"
);
Set(
varLastPartURL,
"?api-version=2016-06-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0&sig=************************************"
);
Set(
varCompleteURL,
varFirstPartURL & varSelectedBatch2.Result & varLastPartURL
);
Launch(varCompleteURL)
Any suggestions?
Thanks!
