Filebeat output to existing index

Elastic Stack Beats
1

Hi everyone,
I'm trying to configure a filebeat output to an existing index but apparently i can't correctly set the template name and pattern.

output.elasticsearch.index: "sai5x"
setup.template.name: "sai5x"
setup.template.pattern: "sai5x"

DevOps created the index for me, and they seem not have used any template, just reindexed documents form an older ES, cause if i GET /sai5x no template is mentioned, and i know they used dynamic mapping.
I've tried creating de index_template i reference in setup.template.name via:

PUT /_index_template/sai5x
{
some_config...
}

But files still get indexed in filebeat-7.12.0.
What am I doing wrong?? Is there a default template used by elastic in these cases?
Thank you in advance.

It'd be useful if you shared your full Filebeat config.

Why, what happens when you do this?

Nothing happens. I expressed my self wrong, it acknowledge: true, but i can't get that template applied to my existing index, cause files keep on going to the default index filebeat created.

Logs show index it's not being set correctly, but don't know why:

I think it'd be useful if you could show your entire Filebeat config please.

Thanks for the answer!
Here you got. I've tried changing the order of the settings, placing index config upper and lower. Also changed from dot notation, to indent (YAML) notation, nothing works. I think the issue is when setting the template cause, like i said, it was created without specifying one.

name: "filebeat:prueba2"
tags: ["filebeat", "prueba"]


filebeat.inputs:
- type: log
  enabled: true
  #tail_files:true
  paths:
    - /var/log/logger.json
  json:  #storing logs as json
    add_error_key: true 
    keys_under_root: true

output.elasticsearch:
  hosts: ["XXXXXXXXXXX:9200"]
  username: "XXXXX"
  password: "XXXXXXXX"
  index: "sai5x-test"
setup.template:
  name: "sai5xa"
  pattern: "sai5xa*"
  type: "index"

logging.level: debug
logging.to_files: true
logging.files:
  path: /home/filebeat
  name: filebeat
  keepfiles: 7
  permissions: 0644

Solved! Had to set setup.ilm.enabled: false
Thank's for the help.
