'Unexpected character' error while executing New-AzPolicyDefinition in Azure Powershell

Question

While trying to create new policy definition using Azure powershell below exception is thrown, kindly let me know if there is error in cmdlet, or the definition file.

New-AzPolicyDefinition : Unexpected character encountered while parsing value: <. Path '', line 0, position 0. At line:1 char:15 + ... efinition = New-AzPolicyDefinition -Name "application-role-tag" -Disp ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : CloseError: (:) [New-AzPolicyDefinition], JsonReaderException + FullyQualifiedErrorId : Microsoft.Azure.Commands.ResourceManager.Cmdlets.Implementation.NewAzurePolicyDefinitionCmdlet

I have used the below command, the policy definition and parameters definition is reference from from azure devops (git) repository,

$definition = New-AzPolicyDefinition -Name "application-role-tag" -DisplayName "Allow resource creation if Application Role tag value in allowed values" -description "Allows resource creation if the Application Role tag is set to one of the following values: webServer, appServer, data." -Policy 'https://company.visualstudio.com/DefaultCollection/Gullfoss/_git/Azure Governance?path=/Policies/Tags/application-role-tag/azurepolicy.rules.json' -Parameter 'https://company.visualstudio.com/DefaultCollection/Gullfoss/_git/Azure Governance?path=/Policies/Tags/application-role-tag/azurepolicy.parameters.json' -Mode Indexed

Policy definition file:

{
    "properties": {
      "displayName": "Allow resource creation if 'application role' tag value in allowed values",
       "policyType": "Custom",
       "mode": "Indexed",
       "description": "Allows resource creation if the 'application role' tag is set to one of the following values: webserver, appserver, data, gateway, messageBroker.",
       "parameters": {},
       "policyRule": {
          "if": {
             "not": {
                "field": "tags['applicationRole']",
                "in": [
                   "webServer",
                   "appServer"                  
                ]
             }
          },
          "then": {
             "effect": "audit"
          }
       }
    }
 }

Policy parameters definition:

{
    "parameters": {}
}

I had wrongly referenced the webpage url instead of fetching the file content using DevOps REST API. The url to fetch file content is as below:

https://dev.azure.com/{organization}/{project}/_apis/sourceProviders/{providerName}/filecontents?repository={repository}&commitOrBranch={commitOrBranch}&path={path}&api-version=5.1-preview.1

{providerName}: tfsgit or tfvs {commitOrBranch}: Name of the branch, such as 'master'
