Here is everything i've wrote :

"inanis:no_exhaustion",
"inanis:end_spawn",

],
"icon": "minecraft:end_crystal",
"order": 10,
"impact": 3,

"description": "Born in the overworld, the Inanis has been cursed by the Master of the end this way they will always wander in his dimension."
}

}

{
"type": "origins:modify_player_spawn",
"dimension": "minecraft:the_end",
"structure": "minecraft:endcity"
}

this is probably due to how you can't modify the search range of spawn locations.
It's only searching the end island (the one with the dragon on it) essentially.
