Databricks API - 无法列出工作区的内容

我尝试使用 databricks API 列出我的用户下的内容。以下是我的代码

`if (-not (Get-PackageProvider -ListAvailable -Name NuGet)) { 
    Install-PackageProvider nuget -Scope CurrentUser -Force
}
if (-not (Get-Module -ListAvailable -Name azure.databricks.cicd.tools)) { 
    Install-Module -Name azure.databricks.cicd.tools -Scope CurrentUser -Force
}

Import-Module -Name azure.databricks.cicd.tools

Function Format-BearerToken ($BearerToken) {
    Return "Bearer $BearerToken"
}

try {
    # Attempt to connect to Databricks
    Connect-Databricks -BearerToken $ADB_Token -Region $region

    # List the content of the user folder
    # Assuming the user folder is "/Users/your.username" - replace with your actual user path
    $userFolderPath = "/Users/[email protected]/"  # Replace with your actual Databricks user folder path

    # Create the body as a hashtable (note the difference in creating a hashtable)
    $body = @{
        path = $userFolderPath
    }
    # Debug: Check the Body that will be sent
    $BodyText = $body | ConvertTo-Json -Depth 10
    Write-Output "Request Body: $BodyText"


    # Test the connection by making an API call to list the workspace contents in your user folder
    $workspaceContent = Invoke-DatabricksAPI -BearerToken $ADB_Token -Region $region `
        -Method GET -API "workspace/list" -Body $BodyText

    # Output the content
    $workspaceContent
}
catch {
    Write-Error "An error occurred: $_"
}`

我的路径参数输出如下所示

Request Body: {
  "path": "/Users/[email protected]/"
}

但我得到了错误

发生错误：无法处理参数“Body”的参数转换。无法将“{"path": "/Users/ [email protected] /"}“System.String”类型的值转换为“System.Collections.Hashtable”类型。

我也尝试过没有 $BodyText = $body | ConvertTo-Json -Depth 10，在这种情况下，我得到了erro code 404 - 404 RESOURCE_DOES_NOT_EXIST Operation was performed on a resource that does not exist.

我的用户名是正确的，并且我确实在其下有一个 test.py 文件。

我有两个问题：

1. 我如何列出内容？2)由于我无法列出内容，我想如果授权成功，但其他情况下我首先会得到401 UNAUTHORIZED The request does not have valid authentication credentials for the operation.- 这是正确的吗？
