Hi, I am running the following script:

add-type "using System.Net; using System.Security.Cryptography.X509Certificates; public class TrustAllCertsPolicy : ICertificatePolicy{ public bool CheckValidationResult(ServicePoint srvPoint, X509Certificate certificate, WebRequest request, int certificateProblem) { return true; }}"; [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; [System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy;

Invoke-WebRequest -Uri '' -Headers @{"authorization" = "Bearer ...." } -OutFile C:\Scripts\defender.ps1;

I returned this error:

Invoke-WebRequest : {"err":""}
At line:1 char:1
+ Invoke-WebRequest -Uri ' ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest], WebException
+ FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

I’m curious whether there’s any recommendation? Thank you.

Did you make another web call to get your token? You will likely need a call to get your bearer token first.
