Error running SQL DB restore using AZ CLI

This is autogenerated. Please review and update as needed.

Describe the bug

When running az backup restore restore-azurewl the error below occurs.

Initially I run az backup recoverypoint list to get a list of recovery points to work with. Then I run az backup recoveryconfig show to create a recovery config JSON file before running az backup restore restore-azurewl using the JSON file. The issue appears to be related to the JSON file but the formatting appears to be correct as the JSON file appears to validate.

Command Name az backup restore restore-azurewl

Errors:

The command failed with an unexpected error. Here is the traceback:

@robnotley We are looking into it and get back to you for any additional information.

@robnotley can you save the JSON output manually into a file instead of using the > c:\github\recovery.json bit, and try the request with that file instead? It appears to be an file encoding issue with the way Powershell < 6 behaves, and not a CLI bug. You can check https://learn.microsoft.com/en-us/powershell/scripting/dev-cross-plat/vscode/understanding-file-encoding?view=powershell-7#configuring-powershell for more details if the workaround works for you.
