PowerShell script for checking links in SharePoint Pages - powershell

Question

I'm trying to check whether every page on a given Sharepoint site contains certain URL with the following PowerShell script. It seems that the foreach loop does nothing at all. Whats should be the reason for this? Also I'm not getting any error messages. I successfully changed some of the list's properties but can't process the data.
#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
#Mysite URL
$site = 'https://contoso.sharepoint.com/sites/contoso'
$urlToFind = "https://google.com"
#Admin User Principal Name
$admin = 'SampleUsername'
#Get Password as secure String
$Password = "SamplePassword"
$SecurePassword = ConvertTo-SecureString -String $Password -AsPlainText -Force
#Get the Client Context and Bind the Site Collection
$context = New-Object Microsoft.SharePoint.Client.ClientContext($site)
#Authenticate
$credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($admin , $SecurePassword)
$context.Credentials = $credentials
$list = $context.Web.Lists.GetByTitle('Pages')
$context.Load($list)
$query = [Microsoft.SharePoint.Client.CamlQuery]::CreateAllItemsQuery()
$Items = $list.GetItems($query)
$context.Load($Items)
$context.ExecuteQuery()
$dataValues = #()
$items.GetEnumerator() | % {
$dataValues += $_.FieldValues
}
$dataValues.Count #determine the amount of items
foreach($item in $dataValues)
{
write-host "inside"
write-host ""
write-host "*** PAGE *** "$item.Url
write-host ""
$file = $item.File
#get binary data, and decode into text
$data = $file.OpenBinary()
$encode = New-Object System.Text.ASCIIEncoding
$text = $encode.GetString($data)
if($text -match $urlToFind)
{
write-warning "FOUND BAD URL IN THIS DOCUMENT!"
}
else {
write-host "nothing found"
}
#comment below to parse all pages
#break
}

We are unable to foreach $list.Items to $item.
We need query $Items by
$Items = $list.GetItems([Microsoft.SharePoint.Client.CamlQuery]::CreateAllItemsQuery())
Then
foreach($item in $Items)
