Fix: Pulumi error Cannot modify this site because another operation is in progress creating Azure Function on Dynamic Consumption plan

Another post which is more to remind me than anything else. When creating an Azure Function in Pulumi, you may get the following error:

Cannot modify this site because another operation is in progress

After a bit of digging, i found this issue on the Pulumi repo, which points to a page on the Azure Functions wiki where they say:

If you run in a dedicated mode, you need to turn on the Always On setting for your Function App to run properly … When running in a Consumption Plan or Premium Plan you should not enable Always On.

The Always On setting for Python is actually part of the constructor of pulumi_azure_native.web.SiteConfigArgs:

(parameter) always_on: Input[bool] | None
always_on: true if Always On is enabled; otherwise, false.

Setting this to true solved the problem.
