Output format is not respected on macOS

[mattias-kindborg-at-work]

Describe the bug

On macOS, after upgrading from Azure CLI v2.29.0 to v2.30.0, output formatting options aren't respected. Formatting options have been verified to work on v2.30.0 running Windows or Ubuntu, but not macOS.

Command Name

All commands where output is formatted, e.g. az group create --name foo --location eastus --output none and az iot hub list --query "[?name=='foo'] | length(@)".

Errors:

Response is always formatted as JSON indifferent of --output argument, and --query with a filter doesn't work at all but instead displays the result as if the query wasn't even applied.

To Reproduce:

Steps to reproduce the behavior. Note that argument values have been redacted, as they may contain sensitive information.

Example 1 where output format isn't respected.

$ az group create --name foo --location eastus --output none
> {
>   "id": "/subscriptions/<id>/resourceGroups/foo",
>   "location": "eastus",
>   "managedBy": null,
>   "name": "foo",
>   "properties": {
>     "provisioningState": "Succeeded"
>   },
>   "tags": null,
>   "type": "Microsoft.Resources/resourceGroups"
> }

Example 2 where query isn't respected, and the response should be the length of the result, not the result itself.

$ az iot hub list --query "[?name=='foo'] | length(@)"
> [
>   { ... },
>   { ... },
>   { ... }
> ]

Expected Behavior

Example 1

$ az group create --name foo --location eastus --output none

Example 2

$ az iot hub list --query "[?name=='foo'] | length(@)"
> 0
