Java Stack Trace logs not displaying with multiline

[Archie_Crawford]

For some reason multiline is not working, its will not display the multiline stack trace in kibana

filebeat.inputs:
- type: log
  enabled: true
  paths:
      - /var/log/*.log
      - /var/log/*messages*
      - /var/log/secure
      - /var/apache-tomcat-8.5.23/logs/catalina*
      - /var/apache-tomcat-8.5.23/logs/*.log

multiline.pattern: '^[[:space:]]+(at|\.{3})\b|^Caused by:'
multiline.negate: false
multiline.match: after
#
filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: true
setup.template.settings:
  index.number_of_shards: 3
setup.kibana:
  host: "xxxxxxx"
output.logstash:
  hosts: ["xxxxxxx"]
processors:
  - add_host_metadata: ~
  - add_cloud_metadata: ~
xpack.monitoring.elasticsearch.hosts: ["xxxxxxx"]

This is my filebeat, I used the multiline on the elasticsearch website but for some reason the mulitline does not show up as it should in kibana
