League of Legends EUW installer

Hello.

I’d like to try out your LoL installer, but I noted that it is for LoL NA server. Thus, I downloaded the json file and edited the links to correctly use the EUW version which is what I need.
Then I ran the script via terminal:

lutris -i /path/to/json/file

The problem is that it raised an error saying that runner field was missing, while I checked and it’s there. Moreover online NA version works and I just edited the links so I’m wondering why it doesn’t work.

Thank you very much
