AttributeError: 'AzureWorkloadJobTaskDetails' object has no attribute 'start_time'

[steffanmartin]

Describe the bug

I can list the backup jobs for a recovery services vault by running

az backup job list --resource-group <Resource Group> --vault-name <Vault Name>

However, when running the command to get the details of a single backup job (with the command below), I encounter an error.

Related command

az backup job show --resource-group <Resource Group> --vault-name <Vault Name> --name <Backup Job ID>

Errors

The command failed with an unexpected error. Here is the traceback:
'AzureWorkloadJobTaskDetails' object has no attribute 'start_time'

az backup job show --ids is also faling with same issue...

I can see the details in the portal inside the vault. Please fix as this is severely impacting how we can work with backups 🙃
