New Post: Cannot convert value "ca.example.com" to type "PKI.CertificateServices.CertificateAuthority"

PS PKI 3.1.0

I managed to get some code working beautifully on my Windows 7 SP1 workstation, but it throws an error when I try to run it locally on my Windows Server 2012 R2 standalone root certificate authority. I think I've narrowed it down to the one line below. I'm so close...so close!

It throws an error on server ca.example.com: Windows Server 2012 R2 (domain-joined standalone root CA)

Import-Module PsPKI
$CertificateRequestResponse = Submit-CertificateRequest -CertificationAuthority "ca.example.com" -Path "\\fs.example.com\path\to\certificates\CertReq.csr"
Submit-CertificateRequest : Cannot process argument transformation on parameter 'CertificationAuthority'. Cannot convert value "ca.example.com" to type

$CertificateRequestResponse

It works fine on workstation wx.example.com: Windows 7 SP1 (domain-joined workstation with RSAT)

Import-Module PsPKI
$CertificateRequestResponse = Submit-CertificateRequest -CertificationAuthority "ca.example.com" -Path "\\fs.example.com\path\to\certificates\CertReq.csr"
$CertificateRequestResponse
