az webapp up - AttributeError: 'ZipFile' object has no attribute 'mkdir'

[jonasheschl]

Describe the bug

When attempting to deploy an ASP.NET Core Web API to Azure App Service, the error AttributeError: 'ZipFile' object has no attribute 'mkdir' is returned. This error occurs when I run az webapp up --name REDACTED --sku F1 --resource-group REDACTED --location germanywestcentral --os-type Linux in the directory of the Web API server.

The ASP.NET Core Web API project is structured like this:

/api-server
  /ApiServerProject <- Deployment command run here
  /ApiServerLib
  api-server.sln
  [...]

Related command

az webapp up

Issue script & Debug output

The generated logs are unfortunately too extensive to reliably check for sensitive information.

Expected behavior

The Web API solution is deployed to azure App Service.

Hi @jonasheschl
Find similar issue #26413.

Issue title	az webapp up AttributeError: 'ZipFile' object has no attribute 'mkdir'
Create time	2023-05-11

Possible solution:
As mentioned in the previous issue, the error occurs due to the lack of the mkdir method in Python 3.10, which is the version bundled with azure-cli. One solution is to upgrade to Python 3.11, which has the mkdir method. Another solution is to wait for azure-cli to bundle Python 3.11.

Please confirm if this resolves your issue.

As far as I can tell, azure-cli is not designed to have its bundled Python interpreter manually swapped out. I also can't find documentation on how swapping the interpreter would work. See #24494.

Adding service team to look into this.

[jonasheschl]

As a temporary workaround, I was able to deploy the project to Azure App Service using the Azure Rider extension.

Any update on this?
