InvalidAuthenticationToken “message”:”The access token is invalid.” – Powershell

The below sample code will make an HTTP call using powershell with Authorization headers. However when you run the code it will fail.

$token =  az account get-access-token | ConvertFrom-Json
$mytoken =  $token.accesstoken
$headers = @{ Authorization = "Bearer $token.accesstoken" }
echo $headers
Invoke-RestMethod -Method Get -Uri "" -Headers $headers -UseBasicParsing

This is an error occuring on powershell as the $token.accesstoken is not correctly parsed. In order to resolve either use a new variable and assign the value on it ($mytoken)

$headers = @{ Authorization = "Bearer $mytoken" }
