Invoke-RestMethod: The remote server returned an error: (401) Unauthorized - Creating new branch

[patritasan]

Steps to reproduce

$json = New-Object -Type psobject
$json | Add-Member -MemberType NoteProperty -Name "name" -Value "refs/heads/release/release01" -Force
$json | Add-Member -MemberType NoteProperty -Name "oldObjectId " -Value "0000000000000000000000000000000000000000" -Force
$json | Add-Member -MemberType NoteProperty -Name "newObjectId " -Value "[ObjectID_MainBranch]" -Force

$jsonBody = ""
$jsonBody += $json | ConvertTo-Json

Invoke-VSTeamRequest -method Post -body $jsonBody -ProjectName "[ProjectName]" -version "5.0" -Area "repositories" -Resource "[Repository_Name]" -Id "refs" -ContentType 'application/json'

Expected behavior

It should create a new branch "release/release01" as a copy of the "main" branch under the repository "[Repository_Name]". Should be the same as executing the API: https://dev.azure.com/[ORG]/[PROJECT_NAME]/_apis/git/repositories/[REPOSITORY_NAME]/refs?api-version=5.0

The PAT used for the connection has "Code (read, write & manage)" permissions. Executing the POST to the URL using same PAT in postman works.

Actual behavior?
