az maintenance assignment create-or-update-subscription command giving unexpected generic error

### Describe the bug

Hi team, previously I have been able to manage the dynamic scope of my maintenance configuration via this command, however I have tried again in the last 2 days and am running into an error, even when using the exact same command and variable values that have worked previously. I have also tested this in two separate subscriptions and am seeing this issue in both.

Example command:
az maintenance assignment create-or-update-subscription --maintenance-configuration-id $maintID --name $maintName --subscription $subID
The variable values are certainly correct strings. See image attached, I have also tried to adjust the parameters specified however that does not seem to help.

I believe configuring dynamic scopes is not possible with Azure Powershell, so that only leaves Azure CLI for me to try to automate this. Could someone please advise if I need to adjust the command or need to be aware of anything else?

Thank you!
