Additional information

I just don't understand why amplify is trying to run yarn. I don't have it. I had it in the past but not anymore!

Hey @programad, thanks for reaching out. The amplify/backend/function/<function-name> should contain a amplify.state file with the build command for the function. you can modify the build command to use a different package manager. The file may be hidden on Vscode, in .vscode/setting.json set the amplify.state as false.
