warnings not being displayed at all

[prankousky]

Hi,

I just installed the plugin and tried the sample json file. None of the errors will be displayed. Even when I insert complete gibberish text and numbers, they will not be recognized as false input.

I tried let g:vim_json_warnings = 1 (which I assume is the standard value anyway, right?), but there is nothing.

I have also looked through the issues here and found somebody's manual snippet to add ti $MYVIMRC, which kinda worked: some errors would be displayed (incorrect colons/semicolons), but not things like this

{
hi mom
afwgwöjng
wef0ü
"something:" somethingles.132
}

this should all be wrong, but nothing got marked as incorrect; same for the sample.json, the errors there would not be marked in red.

What am I doing wrong?

I am using plugged as my plugin manager, use vim_airline and colorscheme onedark, if that is of any help. gvim --version ==> VIM - VI IMproved 8.1 (2018 May 18 compiled Mar 29 2019).

Thanks in advance for your help :)
