Declaring ambigious tuples

[Cnerd]

Hello I am trying to declare ambigious tuples as a type for a field on an 
object type
    
    
    type
        EntryFunctionPayload* = object
            
            moduleid* : ModuleId
            function* : string
            type_arguments* : seq[string] ## tuple of TypeTags ## TODO :: check 
if error occurs here
            arguments* : tuple ## tuple of ScriptArguments
    
    
    Run

I keep getting the error
    
    
    Error: 'tuple' is not a concrete type
    
    
    Run

I need the tuple to be ambigious because it is meant to take multiple different 
unknown values when it is being used. Is there a way to circumvent the error 
message? Thanks
