Upgraded to Pester 5 - now broken :(

Hi,

I have been using a previous version of Pesterto test a load of https APIs. Each API requires a set of headers passed into each request. Previously I was just adding these as a function before and passing the values into the pester test. but now these all fail to run and I’m not sure I understand why.

I’ve added the beforeEach{ and added my function within that script block, but it still fails.

BeforeEach{
    function Get.WebRequest.Headers { 
     [cmdletbinding()]
        param(
    $AccessKey = "##################################",
    $uri = "https://############identity##########/oauth2/default/v1/token",
    $endPoints = (Get-Content .\Pester.Test.Apis.WebRequest\Api.Endpoints.json | ConvertFrom-Json -AsHashtable)
    )
    $Headers = @{}
    $Headers.Authorization = "####################################################"
    $headers.'Content-Type' = "#######################"
    $headers.Cookie = "####################################################"
    $Body = "##############################################"
$R = Invoke-WebRequest -uri $Uri `
                       -Body $body `
                       -Headers $headers `
                       -Method POST 
    $Token = $R.Content | ConvertFrom-Json
    $Token = "Bearer $($token.Access_Token)"
}

}
Describe ‘Testing all environment endpoints’ {
Context ‘API Test against #############’{
foreach ($endpoint in $endPoints.endpoints.#########.Values){
$date = Get-Date
it “$date Testing $endpoint”{
$headers = @{}
$headers.Authorization = “$Token”
$headers."################" = “$AccessKey”
$R = Invoke-WebRequest -Uri $endPoint -Headers $Headers
-Method GET
$R.StatusCode | should be 200
$R
}
}
}

I've cut off the rest of the script cause it does a lot of other stuff, but these tests fail as well as the others.

Any help would be great.

Thanks
