[extension] blueprint version 0.3.2 - Expect <class 'str'>, got ['Owner', 'Contributor', 'Reader'] (<class 'list'>)

[ozbillwang]

Describe the bug

the problem is only in the latest extention version of blueprint v0.3.2

no issue in v0.3.1

Related command

az blueprint version list -m <mgmt_group> --blueprint-name <name>

Errors

When the blueprint version stays as old version, such as 0.3.1, the command is fine

$  az version
{
  "azure-cli": "2.51.0",
  "azure-cli-core": "2.51.0",
  "azure-cli-telemetry": "1.1.0",
  "extensions": {
    "aks-preview": "0.5.149",
    "automation": "0.2.1",
    "azure-devops": "0.26.0",
    "bastion": "0.2.5",
    "blueprint": "0.3.1",
    "communication": "1.7.2b1",
    "express-route-cross-connection": "0.1.1",
    "interactive": "0.5.1",
    "logic": "0.1.7",
    "ssh": "2.0.0",
    "virtual-wan": "0.2.17"
  }
}

But after I upgrade to latest,

az extension add -y --upgrade --name blueprint
Extension 'blueprint' 0.3.1 is already installed.
It will be overridden with version 0.3.2.

The command az blueprint version list xxx failed with an unexpected error. Here is the traceback:

Hi @ozbillwang,

2.51.0 is not the latest Azure CLI(2.52.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

[yonzhan]

Thank you for opening this issue, we will look into it.
