Coding Help Issue using content patcher to edit an image

[PatchouliFleur]

I'm trying to edit the hats sprite sheet using content patcher by overlaying a new texture. The manifest.json seems to work since SMAPI is loading the mod but the changes aren't showing up, could anyone help. content.json below:

{
"Format": "1.29.0",
"Changes": [
{

"Action": "EditImage",
"Target": "Characters/Farmer/hats.png",
"FromFile": "hat.png",
"ToArea": { "X" : 202, "Y" : 400, "Width": 16, "Height": 73 }

},
]
}
