SharePoine Online validate url using powershell

Question

I am trying to validate urls from a link list or other lists with hyper link columns in SharePoint Online.

I tried Invoke-WebRequest method after successfully connecting the SPO site. But this always returns 200 as status code, even for a broken spo link.

Code:

$SPOSiteConnect = Connect-PnPOnline –Url "https://mytenant.sharepoint.com/sites/test1" -ClientId $ClientId -CertificatePath $CertificatePath -CertificatePassword (ConvertTo-SecureString -AsPlainText $pwd -Force) -Tenant $Tenant      

Invoke-WebRequest "https://mytenant.sharepoint.com/sites/test1/Forms/Folders.aspx" -UseBasicParsing      

Any help appreciated.

Thanks Venky.
