I was using the following PowerShell script to update data source connection.
$datasetname="Dashboard Dataset"
$workspacename="REPORT_TEST"
$clientsec = "$(client_secret)" | ConvertTo-SecureString -AsPlainText -Force
$credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $env:client_id, $clientsec
Connect-PowerBIServiceAccount -ServicePrincipal -Credential $credential -TenantId $env:tenant_id
$workspace =Get-PowerBIWorkspace -Name $workspacename
$DatasetResponse=Invoke-PowerBIRestMethod -Url "groups/$($workspace.id)/datasets" -Method Get | ConvertFrom-Json
$datasets = $DatasetResponse.value
foreach($dataset in $datasets){
if($dataset.name -eq $datasetname){
$datasetid= $dataset.id;
break;
}
}
$postParams = @{
updateDetails =@(
@{
name="database"
newValue="db-test"
} ,
@{
name="server"
newValue="server-test"
}
)
} | ConvertTo-Json
Invoke-PowerBIRestMethod -Url "groups/$($workspace.id)/datasets/$($datasetid)/Default.TakeOver" -Method Post
$response=Invoke-PowerBIRestMethod -Url "groups/$($workspace.id)/datasets/$($datasetid)/Default.UpdateParameters" -Method Post -Body $postParams | ConvertFrom-Json
And its giving error
