Issue SMAPI/Content Patcher has an error saying that my Changes field is empty?

I've been trying to make a custom mod for some friends, and it involves replacing a bunch of the characters with custom characters. I unpacked the xnb files, and I can replace the images just fine, but when I try to edit the data and dialogue to change the NPC names I can't get the Content Patcher to properly read the .json files. I'm not great at coding, but I copied the format of the content.json file directly from the instructions and I keep getting a message that my Changes Field is empty and the files can't be loaded.

The SMAPI log looks like this:

[13:11:47 TRACE SMAPI] Disposing the content coordinator. Content managers will no longer be usable after this point.
From what I can tell, it's most likely an issue with my content.json file? But I copied that directly from the information on how to use Content Patcher and only changed the file names, the formatting is unchanged.
This is my content.json:
C#:
{
    "Format": "1.29.4",
    "Changes": [
      {
         "Action": "Include",
         "FromFile": "Assets/NPCDispositions.json"
        }
    ]
}
(It's only got one file at the moment because I want to get it working before I add in the others, but I went through all the character dialogue files too to properly replace the character name)
I would appreciate any advice on how to get this running, I'm not too good at coding. I'm more on the visual side of things when it comes to modding, I can get the sprites to visibly change but I need help with the text
 
I figured it out! Turns out that instead of putting everything in separate .JSON files and having Content Patcher include them, I needed to use the "EditData" action and put the altered text directly in the content.json file. Now it's just a matter of scouring the files for every time a character's name is used and swapping it out, which is intimidating but doable
