In other words, if your custom Startup Command exits<\/em>, Azure stops because there\u2019s no running process.<\/p>\n If Startup Command<\/em> is empty and Azure Web App Service detects your app as Python and Flask powered, the default launch command is For the above launch command to work, your main script needs to be Here's detailed info on the Azure logic: azureossd.github.io\/2023\/01\/30\/Troubleshooting-'failed-to-find-attribute'-errors-on-Python-Linux-App-Services<\/a><\/p>\n Azure will handle it automatically.<\/p>\n Run a Python bot for free on Azure Web App Service Pre-requisite: have a bot.
