The JSON file was previously fully formatted, but now it contains string characters. Everything is working, but to edit something I have to reformat the entire file.
I created a new SetValue and redid the entire process previously done in earlier versions. The result was a complete misconfiguration of the format and several errors.
I've been analyzing it here and the structure of the .json file is correct, but the problem is when we need to add new things to SetValue; then we need to restructure the entire file again.
