Azure function: sporadic and unpredictable failures during code deployment

### Describe the bug

Hello. We are trying to use Azure functions in our project.

I created a pipeline with a script that creates a zip file (size is approximately 10 MB), creates an Azure function, and deploys a zip file into it.

We are running this script using Azure pipelines on an Azure machine. I mean, we are not using self-hosted solutions for this project. So I am sure that zip file is flying from Azure machine to Azure machine in the Azure internal network. Please don't suspect a network issue.

The version of the `az` tool is the latest possible because we are running it on the Azure DevOps machine as a part of the pipeline script.

We have received an issue in the simplest and most reliable part of the script:

```
echo 'Deploy application'
az functionapp deployment source config-zip \
--name '$(FUNCTION_NAME)' \
--resource-group '$(AZ_RG)' \
--src "$APP_PATH"
```

The failing output is the following:
```
Deploy application
WARNING: Getting scm site credentials for zip deployment
WARNING: Starting zip deployment. This operation can take a while to complete ...
WARNING: Deployment endpoint responded with status code 202 for deployment id "***"
ERROR: Failed to connect to 'https://***.scm.azurewebsites.net/api/deployments/***/log' with status code '400' and reason 'Bad Request'
```

I made about 50 deployments and received about 3 failed deployments because of this error. So the **failure rate** for deploying Azure functions is **about 6%**, which is too high!

For now I made a deployment for development purposes only and asked our developers to rerun the pipeline when it fails because of an Azure issue. But tomorrow I will need to make a production deployment, and the customer will ask me a question: why does the pipeline fail?

Can you please provide me a good reason why the chance of successful deployment to Azure Function is so low? So I will resend it to the customer. Because I need to make things clear: this is not my fault; this is Azure's fault. Thank you.

### Expected behavior

The error may appear, but a failure rate of 6% is too high.
