Red line at the end of each line in JSON

[jspdj01]

Hello,
I have red lines at the end of each line in a JSON file that has been formatted.
Could you tell me how I can deactivate these red lines?
THANKS

Most likely the selected syntax is not JSON.

Indeed it is not a json format but it makes the same thing out of thing with json

What I mean is that please select JSON syntax highlighting from the bottom-right of the window.
