Weird mod loading error

[xDefension]

Hello all,
I'm working, as you may expect, on a mod. It's supposed to add a new leader, on the select screen it shows up totally fine but as soon as I press play and it is supposed to switch over to the loading screen, it crashes. I've found this code in the lua log, which seems to show an error:

Runtime Error: C:\Program Files (x86)\Steam\steamapps\common\Sid Meier's Civilization VI\Base\Assets\UI\FrontEnd\LoadScreen.lua:211: operator .. is not supported for nil .. string
stack traceback:
    C:\Program Files (x86)\Steam\steamapps\common\Sid Meier's Civilization VI\Base\Assets\UI\FrontEnd\LoadScreen.lua:211: in function 'OnLoadScreenContentReady'
    [C]: in function 'func'
    [C]: in function '(anonymous)'

I also found this in the database log, which also mentions an error:

Does nobody know how to solve this, or at least what causes it? I've been stuck on this for 3 days now and I've redone the entire thing following the kitty-tempalte as closely as possible, and it still does this..

 

[Infixo]

Line 211 in LoadScreen.lua is:
backgroundTexture = leaderType .. "_BACKGROUND";
leaderType must be nil here.
It is set 2 lines above:
local leaderType:string = playerConfig:GetLeaderTypeName();
So it seems that it's not actually set properly. Which corresponds to DB errors that also show some problems with leader definition.
You need to post the xml where you define the leader.

I think I messed up somewhere, I was using a mod that only changed a leader as a template because that looked like what I wanted to try and create. There was a lot of other crap in the files that I wasn't using or that may have been incomplete so I guess the leader definition error was in there somewhere, but I thought it had something to do with not importing art properly. With the understanding I've gathered from that "experiment" I'm now on track with jasperkitty, so thanks for your help!

Stuck at it again, same error. I've zipped the whole mod so you can look at all the files because my structure is a bit all over the place..

 

[xDefension]

Whilst comparing mine to Jasperkitty I found out this bit in .modinfo was missing:

  <ActionCriteria>
    <Criteria id="LeaderCriteria">
      <LeaderPlayable>StandardPlayers::LEADER_JASPER_KITTY</LeaderPlayable>
    </Criteria>
  </ActionCriteria>

So I pasted it in mine to see if that was the problem, now I no longer crash to desktop but I exit to the main menu and I can't see any indications of errors in any of the logs.. :S

Does this happen when you haven't put in art yet for certain things like leader scenes??

EDIT: I fixed this, but the first leader definition error is STILL a problem, so it would be much appreciated if anyone took a look at it!

There are plenty of mods that add a leader to an existing country, why not just clone it & input your changes? It is probably a lot faster than waiting for people to try & fathom what you have chopped out.
