AZ REST DevOps method returns "az : Not a json response"
I'm running powershell on a windows 10 machine There is trouble running AZ REST method. This script works and was even working with the user account where its now failing and I don't know why. Here is the core function making the AZ REST call.
function getreleasedefinitionrequest($definitionid, $org, $project)
{
$requestpath = "/_apis/release/definitions/" + $definitionid + "?api-version=6.0-preview.4"
$tokeninfo = az account get-access-token | convertfrom-json
$token = $tokeninfo.accessToken
$uribase = "https://vsrm.dev.azure.com/" + $org + "/" + $project
$uri = $uribase+$requestpath
$authheader = "Authorization=Bearer " + $token
$result = az rest --uri $uri --headers $authheader | convertfrom-json
return $result
}
To ensure I'm using an account that has permissions, I'm explicitly logging out and then back in as shown
Az logout –username ‘emailusername’
Clear-AzContext
Connect-AzAccount
az login --only-show-errors --allow-no-subscriptions
Running the AZ REST line of script produces an error

Setting the output to a file doesn't help solve this problem. The output is included below as well.
Thoughts on what is going wrong with this call?

Solution
According to the error, you do not provide the right access token. Because the Azure CLI az account get-access-token just can get access token to get Azure resource or Azure AD resources. It cannot be used to get Azure DevOps access token. For more details, please refer to here and here.
If you want to use CLI to manage Azure DevOps, you can use Azure DevOps CLI. For example, if you want to get release definition, you can use the command az pipelines release definition show.
Update
if you want to use PAT to call Azure devops rest API, please refer to the following script
$username =""
$password="<your PAT>"
$tokens = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username,$password)))
$authheader = "Authorization=Basic " + $tokens
$res = az rest --uri "https://vsrm.dev.azure.com/jim0375/test/_apis/release/definitions?api-version=6.0" --headers $authheader
