'Post in group' with powershell

[TestCICD]

I need to import some files to Power BI using API and powershell

First I create a temporary upload with: groups/group_id/imports/createTemporaryUploadLocation

Then I push my file to the URL

Invoke-RestMethod -Method PUT -Uri \"${url}\" -Header @{ \'x-ms-blob-type\' = \'BlockBlob\'; \'Content-Length\' = $len } -InFile '$myFile' -TimeoutSec 3600

Finally, I try to import that URL to PowerBi using:

Invoke-WebRequest -Method POST -Uri "https://api.powerbi.com/v1.0/myorg/groups/group_id/imports?datasetDisplayName=$myFile&nameConflict=O..." -Header @{Authorization = '$Token'; 'Content-Length' = $len} -Body '{ "fileUrl"= "url"}' | ConvertTo-Json -Depth 5

I am getting the following error: 

Invoke-WebRequest : You must write ContentLength bytes to the request stream before calling [Begin]GetResponse.

 What am I doing wrong? 

EDIT:

After some more research, I found the bellow powershell code to import to PowerBI. It is working but it won't let me import larger file 900,000KB

I also still need to find out how to get the files from azure...
