[johlju]

Details of the scenario you try and problem that is occurring:
If parameter UpdateSource is set to a value and UpdateEnabled is set to 'False' then the setup fails without an error. The setup ends quickly without an error, and after htat the resource reports from the Test-method that no features was found and the resource errors out.

The DSC configuration that is using the resource (as detailed as possible):

xSQLServerSetup $resourceConfigName
{
    InstanceName = $Node."$($currentSqlInstance)InstanceName"
    Features = $Node."$($currentSqlInstance)InstallFeatures"
    BrowserSvcStartupType = 'Automatic'
    SQLCollation = 'Finnish_Swedish_CI_AS'
    SQLSvcAccount = $SqlServiceCredential
    AgtSvcAccount = $SqlAgentServiceCredential
    #ASSvcAccount = $SqlServiceCredential
    SQLSysAdminAccounts = 'COMPANY\SQLAdmins', $SqlAdministratorCredential.UserName
    SetupCredential = $SqlInstallCredential

    SourcePath = $Node."SourcePath$($currentSqlInstance)"
    SourceCredential = $SqlInstallCredential

    UpdateEnabled = 'False'
    UpdateSource = '.\Updates'

    SuppressReboot = $false
    ForceReboot = $false

    DependsOn = '[WindowsFeature]NetFramework45'
