syslog-ng kafka destination error: Error parsing config, syntax error, unexpected LL_IDENTIFIER, expecting '}'

Question

I am trying to set up a Kafka destination in syslog-ng, but encoutering the following error:

Oct 09 17:44:20 ip-172-31-0-228 syslog-ng[241321]: Error parsing config, syntax error, unexpected LL_IDENTIFIER, expecting '}' in /etc/syslo>

Oct 09 17:44:20 ip-172-31-0-228 syslog-ng[241321]: 16      };

Config file:

source s_net {
    udp(port(514));
};

destination d_file {
    file("/var/log/syslog-ng/test.log");
};

destination d_kafka {
    kafka(
        topic("syslog")
        bootstrap-servers("172.31.0.228:9094")
    );
};

log {
    source(s_net);
    destination(d_file);
    destination(d_kafka);
    level(debug);
};

Kafka also present in available modules:

Available-Modules: map-value-pairs,afprog,basicfuncs,afsocket,sdjournal,kafka,rate-limit-filter,cryptofuncs,linux-kmsg-format,pacctformat,hook-commands,timestamp,pseudofile,syslogformat,affile,json-plugin,system-source,tags-parser,tfgetent,confgen,disk-buffer,afuser,cef,csvparser,kvformat,regexp-parser,appmodel

As far as I can see the everything is correct, does anyone have an idea what I am missing?
