PowerShell DSC Invalid MOF definition for node 'localhost' - powershell

Question

As I'm new to PowerShell and also DSC (and programming in total) i have a question to which i couldn't find an answer in the web.
I'm trying to install an msi (or an exe) with PS DSC. I sucessfully wrote a script to check and install windows-features and to install JDK and set the ressources.
But with my next step I seem to be overchallenged.
so heres my code so far:
$ConfigurationData = #{
AllNodes = #(
#{
NodeName="*"
PSDscAllowPlainTextPassword=$true
}
)
}
Configuration AppFabric
{
param (
$TargetNodes,
[Parameter(Mandatory=$false)]
[PSCredential]$Credential
)
Import-DscResource –ModuleName ’PSDesiredStateConfiguration’
Node localhost
{
Package AppFabric
{
Ensure = "Present"
Name = "AppFabric"
Path = "$PWD\src\AppFabric\package\appfabric-1.1-for-windows-server-64.msi"
ProductId = ""
LogPath = "$PWD\logs\$env:computername-AppFabric"
Arguments = "/i HostingServices,CacheClient,HostingServicesAdmin"
Credential = "$Credential"
}
}
}
AppFabric -OutputPath $PWD\mof\AppFabric\
Start-DscConfiguration -Path $PWD\mof\AppFabric\ -wait -verbose -Force
So as you see i'm trying to install AppFabric on a Windows Server 2012R2 up to date.
When i Run the script i get following error:
I have no clue, what that means and can't find anything on the web that could help.
If you need further information, let me know, as I said, I'm new to this :x
Thanks!
Edit:
If I try to do it without credentials I get the following:
VERBOSE: Perform operation 'Invoke CimMethod' with following parameters, ''methodName' = SendConfigurationApply,'className' = MSFT_DSCLocalConfigurationManager,'namespaceName' = root/Microsoft/Windows/DesiredStateConfiguration'.

You are treating the Credential property as a string instead of PSCredential.
Remove double quotes from Credential property to fix the issue.
Package AppFabric
{
Ensure = "Present"
Name = "AppFabric"
Path = "$PWD\src\AppFabric\package\appfabric-1.1-for-windows-server-64.msi"
ProductId = ""
LogPath = "$PWD\logs\$env:computername-AppFabric"
Arguments = "/i HostingServices,CacheClient,HostingServicesAdmin"
Credential = $Credential
}
