Builder Repo Start - Killed code 137 ☠️☠️ - Step by Step with images

Hi Sir! :slightly_smiling_face:

Trying to start the Builder repo on my ubuntu 20.4 server.

Getting a error 137 back.

Here the commands i do:

Step 1: Navigate to the folder were i cloned the repo

cd /var/www/builder

Step 2: I install the decentraland compiler + run install command

npm i decentraland-rpc
npm install

Step 3: I rename the .env file

mv .env.example .env

Step 4: I open and edit the .env variables

nano .env 

Step 5:

Step 6: I start

npm start

Step 7: Error message code 137

Step 8: I open the log

cd /root/.npm/_logs/2021-11-20T06-_21_05_501Z-debug.log

Step 9: The log is empty

Did i took for granted some step perhaps?
Any Hint?

Thanks so much!
