Errors adding Environment Variables to NodeJS Elastic Beanstalk

Question

My configuration worked up until yesterday. I have added the nginx NodeJS https redirect extension from AWS. Now, when I try to add a new Environment Variable through the Elastic Beanstalk configuration, I get this error:

[Instance: i-0364b59cca36774a0] Command failed on instance. Return code: 137 Output: + rm -f /etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf + service nginx stop Stopping nginx: /sbin/service: line 66: 27395 Killed env -i PATH="$PATH" TERM="$TERM" "${SERVICEDIR}/${SERVICE}" ${OPTIONS}. Hook /opt/elasticbeanstalk/hooks/configdeploy/post/99_kill_default_nginx.sh failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.

When I look at the eb-activity.log, I see this error:

[2018-02-18T17:24:58.762Z] INFO  [13848] - [Configuration update 1.0.61@112/ConfigDeployStage1/ConfigDeployPostHook/99_kill_default_nginx.sh] : Starting activity...

What am I doing wrong? And what has changed recently since this worked fine when I changed an Environment Variable a couple months ago.

I had this problem as well and Amazon acknowledged the error in the documentation. This is a working restart script that you can use in your .ebextensions config file.

  /opt/elasticbeanstalk/hooks/configdeploy/post/99_kill_default_nginx.sh:
    mode: "000755"
    owner: root
    group: root
    content: |
      #!/bin/bash -xe
      rm -f /etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf
      status=`/sbin/status nginx`

      if [[ $status = *"start/running"* ]]; then
        echo "stopping nginx..."
        stop nginx
        echo "starting nginx..."
        start nginx
      else
        echo "nginx is not running... starting it..."
        start nginx
      fi
