Additional files not being deployed on add-on installation

[XFFA.IR Bot]

I've added some directories to my add-on, however is not being deployed on installation.

Am I missing something?

build.json

Code:

{
  "additional_files": [
    "js/My/Addon",
    "styles/My/Addon",
    "data/My/Addon/Images"
  ]
}
