Today I created a new configuration data for a DSC configuration and got the following error: all elements of AllNodes need to be hashtable and has a property ‘NodeName’. The config looked good:
$ConfigurationData = @{
AllNodes = @(
@{
DeploymentPath = "$(${env:ProgramFiles(x86)})\Company\MyProject"
ServiceName = "NameOfService"
DisplayName = "Display name of the service."
}
@{
NodeName = $env:Computername
}
);
}
AllNodes was a hashtable and it had the desired node name. So where was the error?
I forgot one little thing: the global configuration needs a property NodeName set to an asterisk. Adding this fixed the error.
$ConfigurationData = @{
AllNodes = @(
@{
NodeName = "*"
DeploymentPath = "$(${env:ProgramFiles(x86)})\Company\MyProject"
ServiceName = "NameOfService"
DisplayName = "Display name of the service."
}
@{
NodeName = $env:Computername
}
);
}
This is really easy – but a search for the error message did not return any useful results. Therefor I decided to share it anyway…
