DXA .NET 1.4, error with script ttm-prepare.ps1

Question

I started the DXA install following the steps from the documentation but got stuck with the following error. I however proceeded with next step to import and that worked fine.

I get a rather strange error which says it cannot convert System.Object[] to the type System.String?

I looked into the script, it is trying to split the baseUrls. Is it expecting more URLs here? I tried comma separated -> dxastaging, dxalive and http://dxastatging, http://dxalive etc. but it didn't work.

do { $baseUrls = Read-Host "Enter DXA '$($cdEnvironment.EnvironmentPurpose)' Website Base URL(s)" }
            until ($baseUrls)
            $baseUrls = $baseUrls.Split(",")
            $website = Add-TtmWebsite -CdEnvironmentId $cdEnvironment.Id -BaseUrls $baseUrls -ErrorVariable cmdletError

Answer 1

Looking at the PowerShell error message, the problem seems to be in the CdEnvironmentId parameter of the Add-TtmWebsite command. So, in the value of $cdEnvironment.Id. Does your CD Environment ID contain a comma? PowerShell may then misinterpret it as an array of strings instead of a single string.

I did notice that your CD Environment has a quite remarkable purpose "Staging Staging" (what's wrong with just "Staging" ? :-) So maybe it also has a weird ID?

Answer 2

A Base URL should be a valid URL, so not dxastaging (which is a host or domain name), but http://dxastaging, or http://localhost, or http://staging.site.com (including port if not 80).

If you want to provide multiple Base URLs, then separate them with a comma, not a comma and a space, so http://dxastaging,http://dxalive.

I agree that this information should be added to the documentation, since currently it only states you should run the script.
