Error 400 - Bad Request for import api call

[parviz_asoodehfard]

I can't find the reason this command in powershell raise an error

$hdrs = @{}
$hdrs.Add("X-Qlik-xrfkey","1234567890123456")
$hdrs.Add("X-Qlik-User","UserDirectory=XXXXX;UserId=XXXXXXXXXXXXXX")

$cert = Get-ChildItem -Path "Cert:\CurrentUser\My" | Where {$_.Subject -like '*QlikClient*'}

$Body = @{
filename="test_import.qvf"
} | ConvertTo-Json

$url = "https://XXXXX.XXXXXX.XXX:4242/qrs/app/import?name=test_import&xrfkey=1234567890123456"
$response = Invoke-RestMethod -Uri $url -Method POST -Headers $hdrs -Certificate $cert -Body $Body -ContentType 'application/json'
$response

Error:

This works for me:

$hdrs = @{}
$hdrs.Add("X-Qlik-Xrfkey","examplexrfkey123")
$hdrs.Add("X-Qlik-User", "UserDirectory=INTERNAL; UserId=sa_api")
$cert = Get-ChildItem -Path "Cert:\CurrentUser\My" | Where {$_.Subject -like '*QlikClient*'}
$Data = Get-Content C:\ProgramData\Qlik\Sense\Host.cfg
$FQDN = [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($($Data)))
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12' 
Invoke-RestMethod -Uri "https://$($FQDN):4242/qrs/app/upload?keepData=true&name=Some+Name&xrfkey=examplexrfkey123" -Method Post  -Headers $hdrs -ContentType 'application/vnd.qlik.sense.app' -Certificate $cert -InFile 'C:\Temp\Random Data.qvf'
