Code doesn't work

### Reference command name

az dataprotection backup-instance validate-for-restore

### Feedback

Trying the **az dataprotection backup-instance validate-for-restore command** followed by the **dataprotection backup-instance restore trigger** command results in the following error:

`Info: {
"message": "The current operation failed due to an internal service error \"Invalid input error\". Please retry the operation after some time.",
"recommendedAction": [
"If the issue persists, please contact Microsoft support."
],
"code": "CloudInvalidInputError",
"target": "",
"isRetryable": false,
"isUserError": false,
"properties": {
"ActivityId": "13752020-f451-11ef-8ec2-39b6726f401a"
}
}:`

Performing the command after some time doesn't seem to help. Can we confirm if the command is working correct as it should?
