AutoSPInstallerModule.psm1 - Line 2882 - Fails to get existing web app for HNSC on multiple servers

Line 2882 - AutoSPInstallerModule.psm1:
$getSPWebApplication = Get-SPWebApplication -Identity $fullUrl -ErrorAction SilentlyContinue

Should be:
$getSPWebApplication = Get-SPWebApplication -Identity $webAppName -ErrorAction SilentlyContinue

This way it will pick up the web application using the name instead of url, which for host named site collections is created using the machine name.

This also affects lines 2917 and 2924:
$wa = Get-SPWebApplication -Identity $fullUrl

should be
$wa = Get-SPWebApplication -Identity $webAppName

Line 2994:
New-SPContentDatabase -Name $siteDatabase -WebApplication (Get-SPWebApplication -Identity $fullUrl

should be:
New-SPContentDatabase -Name $siteDatabase -WebApplication (Get-SPWebApplication -Identity $webAppName

Specified in my installer config is:

    <WebApplication Name="Portal">
        <Type>Portal</Type>
        <ApplicationPool>SharePoint2019.serverfarm.CA</ApplicationPool>
        <Url>http://localhost</Url>

The localhost is being translated in the script to be the server running it. Perhaps this is not the best practice?

It's not best practice to use the server name or http://localhost as a SharePoint URL. Use a real DNS name instead, different from the server name.

What is your scenario? I build multi server environment over the weekend but have not seen this issue. Any thing different may be ? Get Outlook for Android<https://aka.ms/ghei36>
