Receive 404 Not Found errors during zip deploy every so often

[kamranayub]

I've been working most of the day with an Azure Function and have done about 20+ deployments. It seems like every other one, or once every 3-4 times, I get the following error. If I just re-run the failed job, it'll work.

Node v18 / Linux Consumption Plan / Oryx Build / SCM Do Build During Deployment

Has anyone experienced this?

Could you solve this @kamranayub? I m seeing the same in our project since today. It was working for 2 years and also today and suddenly without any relevant changes it fails every deployment.

[kamranayub]

@martin-greentrax no unfortunately but mainly it's because the Az function I had won't work for my purposes anyway so I stopped deployments. Since then I have not looked into it further.

The same issue did go away for me after experimenting for a long time. Hope this helps someone else googling:

• I did add the environment variables that are suggested in other threads about the issue (like ENABLE_ORYX_BUILD and SCM_DO_BUILD_DURING_DEPLOYMENT) but can't say that they helped
• Go to your function on portal.azure.com and in the Overview blade at the bottom click on your Function "app"
  I see this message there:
  "Your app is currently in read only mode because you are running from a package file. To make any changes update the content in your zip file and WEBSITE_RUN_FROM_PACKAGE app setting."
• I clicked on Disable
• Then added WEBSITE_RUN_FROM_PACKAGE=0 in the blade Environment variables (it was not part of the variables before)
  Restarted the function, enabled the "app" again and my github job went through again finally
