Import Dataflow in Power BI Service

I use this script to import a dataflow : 

$credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList "...", ("..." | ConvertTo-SecureString -AsPlainText -Force)

Connect-PowerBIServiceAccount -ServicePrincipal -Tenant "..." -Credential $credential -Environment "Public"

$workspaceName = "WKS - DTS [DEV]"

$DataflowImportFileName = "C:\Users\cbonier\Documents\DTF FINANCE.json"

$DataflowDefinition = [IO.File]::ReadAllText($DataflowImportFileName)

$UserAccessToken = Get-PowerBIAccessToken
$bearer = $UserAccessToken.Authorization.ToString()

$workspace = Get-PowerBIWorkspace -Name $workspaceName
$workspaceId = $workspace.Id

$importsUrl = "$workspaceId/imports?datasetDisplayName=DTF FINANCE.json"

$boundary = [System.Guid]::NewGuid().ToString("N")
$LF = [System.Environment]::NewLine

$contentType = "multipart/from-data; boundary=""$boundary"""

$body = (
"Content-Disposition: form-data $LF",
) -join $LF

$header = @{
    'Authorization' = "$bearer"
    'Content-Type' = "$contentType"

Invoke-RestMethod -Uri $importsUrl -ContentType $contentType -Method Post -Headers $header -Body $body

 But I have this error :

Hi @v-chenwuz-msft


What do you mean when you write : "This parameter should be hardcoded to model.json." ? 


I tried this script but it doesn't work :

Invoke-PowerBIRestMethod -Url "" -Method Post


Error message : 

AVERTISSEMENT : The Body parameter was null, the request may be invalid when Method par
ameter is Post.

Hi @Anonymous ,



This parameter should be hardcoded to model.json.
