Can't download app content of azure function via portal

Question

How do I download the source code of already-deployed Azure functions? The person who deployed this function has not versioned it in a repo yet, and the button is grayed out in the portal, as you can see.

Answer 1

What works:

• Log into azure
• New tab
• Go to https://FUNCTION_APP_NAME_HERE.scm.azurewebsites.net/api/settings
• copy content of SCM_RUN_FROM_PACKAGE (which is a link)
• another tab, go to http://... (the link given as SCM_RUN_FROM_PACKAGE)
• you get a file with .zip extension, but it's not a ZIP
• brew install squashfs (or whichever installer you need for your platform)
• unsquashfs $zipfile
• you have a new folder squahsfs-root
• mv sqhashfs-root $(basename $file .zip)
• (done)
