Event to give bloodline to a few random characters?

[Whitewatt]

Hello.

It's the first time I'm delving into event modding and I'm not sure what to do.
I want to create an event that fires on start up for only a few catholics with zealous trait (like 3 tops) to make them a member of a specific bloodline.

How do I go about achieving this?

Thank you for reading.

I tried making the event by look at wiki and examples, but the validator gives me an the error:
Invalid node "random" in scope CharEvent (value is: <a complex type>)

I tried searching google for this but there's barely any references to Invalid nodes and none to
"random" or in scope CharEvent, so idk what to do.

This is the event:

namespace = BOJ

character_event = {
    id = BOJ.1
  
    hide_window = yes
    is_triggered_only = yes
    religion = catholic
  
    trigger = {
        has_dlc = "Holy Fury"
        trait = zealous
    }
  
    random = {
        chance = 5
        add_to_bloodline = bloodlineblab
    }         
}

EDIT:

I put random inside immediate and that error no longer shows. Now I get "bloodlineblab" is not a valid MaybeEventTarget(bloodline).

How do I fix that?

EDIT 2:

Ignore this thread, posted on the quick help thread and got it fixed;

any_bloodline = {
    limit = { has_bloodline_flag = <flag> }
    ROOT = { add_to_bloodline = PREV }
}
