Hi,
As the input is coming from the Booking wizard rather then the passed volatile profile instances, there is another way to read the actual values from the booking wizard:

1. Your automation script should receive as input 3 values: "Info", "ProfileInstance" and "ProcessInfo".
2. Deserialize the input "Info" to have a SrmResourceConfigurationInfo object and the input "ProfileInstance" to have a Dictionary containing all the profile instances.
3. Create a new instance of ProfileParameterEntryHelper(Engine engine) and collect all the parameters with .GetNodeProfileParameterEntries().

I've included a small code snipped that should let you receive the list of parameters with the values you've specified in the booking wizard.

ScriptParam paramInfo = engine.GetScriptParam("Info");
ScriptParam paramProfileInstance = engine.GetScriptParam("ProfileInstance");
ScriptParam paramProcessInfo = engine.GetScriptParam("ProcessInfo");

var srmInfo = JsonConvert.DeserializeObject<SrmResourceConfigurationInfo>(paramInfo.Value);
if (srmInfo == null)
{
throw new ScriptInputValueNullException("SRM Info is null or is not in the correct format (Serialize SrmResourceConfigurationInfo to JSON).");
}

var srmNodeProfileConfiguration = JsonConvert.DeserializeObject<Dictionary<string, Guid>>(paramProfileInstance.Value);
if (srmNodeProfileConfiguration == null || !srmNodeProfileConfiguration.Any())
{
throw new ScriptInputValueNullException("ProfileInstance is null or is not in the correct format (Serialize Dictionary<string, string> to JSON).");
}

var helper = new ProfileParameterEntryHelper(engine);
List<ProfileParameterEntry> parameters = helper.GetNodeProfileParameterEntries(srmInfo, new NodeProfileConfiguration(srmNodeProfileConfiguration), true).ToList();
