Nested exceptions during failure of azure function deployment

[andrew-slutsky]

Information

• Onefuzz version: 1.3.0
• OS: Windows

Provide detailed reproduction steps (if any)

1. Execute a deployment using a poor internet connection or induce an exception (e.g. kill func.exe) while subprocess "func azure functionapp publish ..." is running.

Expected result

I expect to see only the Azure.Functions.Cli.Common.CliException exception or reason displayed and not a PermissionError.

Traceback (most recent call last):
File "deploy.py", line 789, in
main()
File "deploy.py", line 783, in main

File "deploy.py", line 604, in deploy_app

output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['C:\ProgramData\chocolatey\bin\func.EXE', 'azure', 'functionapp', 'publish', '', '--python', '--no-build']' returned non-zero exit status 1.

Actual result

During handling of the above exception, another exception occurred:
