Connect-PowerBIServiceAccount getting error in power shell script

I need to connect POWER BI account without prompting and password would be secure not in script file .

Below is the powershell script :

Clear-Host
$PSScriptRoot= "D:\powershell"
$pathFile = $PSScriptRoot + "\logs\"
$pwdpath = $PSScriptRoot + "\pwd\"
$pwdfile = $pwdpath + "creds.xml"

<# Get password from file, if file exists. Else, create folder and export params after prompted to user. #>

if(Get-Module -Name MicrosoftPowerBIMgmt -ListAvailable){
#Update-Module MicrosoftPowerBIMgmt -Force
}else{
Install-Module MicrosoftPowerBIMgmt -Scope CurrentUser -Force
}

if([System.IO.File]::Exists($pwdfile)){
$mycreds = Import-CliXml -Path $pwdfile
} else {
if(!([System.IO.File]::Exists($pwdpath))){
New-Item -Path $PSScriptRoot -Name "pwd" -ItemType Directory
}
Get-Credential | Export-CliXml -Path $pwdfile
$mycreds = Import-CliXml -Path $pwdfile
}
Connect-PowerBIServiceAccount -Credential $mycreds

It throws an error :

Connect-PowerBIServiceAccount : One or more errors occurred.
