az iot dps enrollment update --allocation-policy static --iot-hubs new-iothub inserts an additional_properties to the initial twin

[absoluteSloth]

Describe the bug

When changing the statically assigned iothub for a single device enrollment, the initial twin properties get all copied under a key named additional_properties.
We would expect that this optional value would be untouched by the command.

There is a workaround where you query the current initial-twin-properties and set it with the command.

Related command

Failing command:
az iot dps enrollment update -g "$RG" -n "$DPS" --enrollment-id "$ID" --allocation-policy static --iot-hubs "$NEW_IOT_HUB" --output none

Workaround:

TWIN=$(az iot dps enrollment show -g "$RG" -n "$DPS" --enrollment-id "$ID" --query "initialTwin.properties.desired")
az iot dps enrollment update -g "$RG" -n "$DPS" --enrollment-id "$ID" --allocation-policy static --iot-hubs "$NEW_IOT_HUB" **--initial-twin-properties "$TWIN"** --output none

Errors

The initial twin is polluted with an additional_properties

Hi @absoluteSloth,

2.71.0 is not the latest Azure CLI(2.74.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

[yonzhan]

Thank you for opening this issue, we will look into it.

2.71.0 is not the latest Azure CLI(2.74.0).

I retried it with the latest 2.74.0 version and it still fails the same way.

Thanks for reporting, I will take a look and try to repro

Any update?

Hi @absoluteSloth,

Sorry for the long delay. I have looked into your issue and managed to find the bug (it also affected other params/commands too). I created a pull request with the bug fix, which should go in sometime this week.

We will be releasing a new version of the azure-iot-extension sometime soon so until then, please use the work around. I will let you know when the new version is released.

Ps: love your username
