Parse JSON file to dictionary

Actually, I’ve already read this topic and tried this extension with the file component.
But the result was not good :confused:

My goal is, at the first run, to read the json file, put it in a dictionnary and store the dictionary in TinyDB.
On next runs, only have to get valur from TinyDB.

I try to mix this 2 examples (taken from Simple use of dictionary and TinyDB)
