Hi , I got the following error when I try to deploy application using Azure devops technique ,

after I connect azue with github and connect it with my application I opened YML file

then I add task "Azure app service deploy"

but I got the following error when I select Azure subscription and click authorize button

"Service connection with name Windows Azure MSDN - Visual Studio Premium(xxxxxxxxxxxxxxxxxx) already exists. Only a user having Administrator/User role permissions on service connection Windows Azure MSDN - Visual Studio Premium(xxxxxxxxxxxxxxxxxx) can see it."

please check attached photo for more clarification

The error message suggests that the service connection already exists and that you may not have the appropriate permissions to view or modify it.
Goto > Project settings>Service connections >Pipelines Check if the "Windows Azure MSDN - Visual Studio Premium" service connection already exists. If it exists, you'll need to ensure you have the right permissions if not adjust the permissions in Security.
