having problems on trying to change this.obj['name.ext'].value

[jetrotal]

I'm trying to run this code on cmd
json -I -f rtpData.json -e "this.CharSet['Object1.png'].status = 'wip'"
it prints the json file was updated, but nothing changes on the code.

Looks like the problem is with "Object1.png" part of the command. Any suggestion on how to run this command properly without having to rename "Object1.png"?
