Failed to bootstrap error - problem with pups

I’ve definitely narrowed it down to this file, which is for sure causing the boot failure -

/var/discourse/templates/web.ratelimited-whitelist.template.yml

which I’m pasting below (with IPs redacted):

params:
  reqs_per_second: 12
  burst_per_second: 12
  reqs_per_minute: 200
  burst_per_minute: 100
  conn_per_ip: 20

run:
  - replace:
    filename: "/etc/nginx/conf.d/discourse.conf"
    from: /server.+{/
    to: |
       geo $limit {
           default 1;
           XX.YYY.ZZ.ZZZ 0; # hubprod
           XXX.YY.ZZZ.ZZZ 0; # hubdev
       }

       map $limit $limit_key {
           0 "";
           1 $binary_remote_addr;
       }

       limit_req_zone $limit_key zone=flood:10m rate=$reqs_per_secondr/s;
       limit_req_zone $limit_key zone=bot:10m rate=$reqs_per_minuter/m;
       limit_req_status 429;
       limit_conn_zone $limit_key zone=connperip:10m;
       limit_conn_status 429;
       server {
  - replace:
    filename: "/etc/nginx/conf.d/discourse.conf"
    from: "/location @discourse {/"
    to: |
       location @discourse {
         limit_conn connperip $conn_per_ip;
         limit_req zone=flood burst=$burst_per_second nodelay;
         limit_req zone=bot burst=$burst_per_minute nodelay;

Is there anything in the run command here that looks off? YAML linting still looks OK.
