Bash issues does recognize app service, but it's clearly running I've tried multiple ways,

Hi Dennis,

"run" is not needed in your case (Azure CLI). You should only use "az webapp deployment" and remove the "run".
You will find more information for the Azure CLI on this page : https://learn.microsoft.com/fr-fr/cli/azure/webapp/deployment?view=azure-cli-latest

I hope I have helped you and wish you a nice day

Nicolas
