"That position is not loaded" anyone know why?

I'm trying to place a custom structure in the end that's 7x7 wide and 6 blocks tall at the position -3 65 -3. Command: /place template 1block:end_portal_base -3 65 -3
I was in the end when I typed the command, and even forceloaded the position. It doesn't work when used in a datapack with the /execute in the_end command. I tried adding a layer of light blocks in the dimension/the_end.json file and that didn't work. I was able to manually place it with a physical structure block in the exact position perfectly, and I can run fill and setblock commands perfectly as well.
Is it because something I changed the dimension or dimension_type json?
dimension/the_end.json 
  "type": "minecraft:the_end",
  "generator": {
    "type": "minecraft:flat",
    "settings": {
      "biome": "minecraft:the_end",
      "layers": [
      ]
    }
  }
}```
