Issue what can I possibly do with this..?

(I must apologize for bad English.)
I don’t really understand how can I fix this error.

(This pic is from when I run Stardew valley(1.6) using SMAPI(4.0))

Here is the log if needed:

JSON validator (Content Patcher, 15f84a576eeb4f09bcc7b94c70bc9521) - SMAPI.io

I’m not really sure of what should I pointed out in my log since it seems like everything is fine(?)

I’ve never added a full character before, but I believe your tile location is incorrect.
Instead of: "Tile": "22, 5",
it should be: "Tile": { "X": 22, "Y": 5 },

Thank you so much for your help, it works.
