Create partition via powershell error

[poweruser1]

I am trying to write a Powershell script to create a partition in a Power BI dataset. Anyone know how to resolve this error? I am receiving the following error:

My Powershell Code:

$m_code = "let
Source = Sql.Database(`"source`", `"db`", [Query=`"sel column form table`", CommandTimeout=#duration(0, 1, 0, 0)])
in
Source"

$tmsl = "{
`"create`": {
`"parentObject`": {
`"database`": `"model name`",
`"table`": `"Table name`"
},
`"partition`": {
`"name`": `"test partition`",
`"source`": {
`"type`": `"m`",
`"expression`": [
`"$m_code`"
]
}
}
}
}"

invoke-ascmd -Server "powerbi://api.powerbi.com/v1.0/myorg/workspace" -Database "model Name" -Query $tmsl

Hi @poweruser1,

Perhaps you can take a look the following sample code if it help with your scenario:

$groupID = "<your group ID>"
$datasetID = "<your dataset ID>"
$token = Get-PowerBIAccessToken
$authHeader = @{ "Authorization" = "Bearer $token" }
$uri = "https://api.powerbi.com/v1.0/myorg/groups/$groupID/datasets/$datasetID/Partitions"
$body = @{
    "name" = "ImportName"
    "mode" = "Import"
    "source" = @{
        "type" = "Query"
        "query" = "SELECT * FROM $tableName"
        "dataSource" = @{
            "type" = "Sql"
            "connectionDetails" = @{
				"server" = "$serverName.database.windows.net"
				"database" = "$databaseName"
                "authentication" = "Windows"
            }
        }
    }
}
$jsonBody = $body | ConvertTo-Json
Invoke-RestMethod -Uri $uri -Headers $authHeader -Method Post -Body $jsonBody
