Start at the Get-AzContainerAppJobExecution entry point and compare its returned object with the properties shown in the 2023-05-01 REST response. Verify that fields such as Status and StartTime are exposed and appear in ToJsonString(); done means the execution object contains the response properties reported in the issue.
