No data has been received from Functionbeat yet

[spo]

Hi,
I have installed and configured functionbeat on the elk server.
Installation and configuration was successful but unable to pull logs on kibana.

functionbeat.yml :

functionbeat.provider.aws.endpoint: "s3.amazonaws.com"
# Configure which S3 bucket we should upload the lambda artifact.
functionbeat.provider.aws.deploy_bucket: "abcde"

functionbeat.provider.aws.functions:
  # Define the list of function availables, each function required to have a unique name.
  # Create a function that accepts events coming from cloudwatchlogs.
  - name: cloudwatch-logs
    enabled: true
    type: cloudwatch_logs

    # List of cloudwatch log group registered to that function.
    triggers:
      - log_group_name: abcdef

# This requires a Kibana endpoint configuration.
setup.kibana:

  # Kibana Host
  # Scheme and port can be left out and will be set to the default (http and 5601)
  # In case you specify and additional path, the scheme is required: http://localhost:5601/path
  # IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
  host: "pri.ip:5601"

  # Kibana Space ID
  # ID of the Kibana Space into which the dashboards should be loaded. By default,
  # the Default Space will be used.
  #space.id:

# =============================== Elastic Cloud ================================

# These settings simplify using Functionbeat with the Elastic Cloud (https://cloud.elastic.co/).

# The cloud.id setting overwrites the `output.elasticsearch.hosts` and
# `setup.kibana.host` options.
# You can find the `cloud.id` in the Elastic Cloud web UI.
#cloud.id:

# The cloud.auth setting overwrites the `output.elasticsearch.username` and
# `output.elasticsearch.password` settings. The format is `<user>:<pass>`.
#cloud.auth:

# ================================== Outputs ===================================

# Configure what output to use when sending the data collected by the beat.

# ---------------------------- Elasticsearch Output ----------------------------
output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["http://pri.ip:9200"]

  # Protocol - either `http` (default) or `https`.
  #protocol: "https"

  # Authentication credentials - either API key or username/password.
  #api_key: "id:api_key"
  username: "******"
  password: "**********"

# Available log levels are: error, warning, info, debug
logging.level: debug

# At debug level, you can selectively enable logging only for some components.
# To enable all selectors use ["*"]. Examples of other selectors are "beat",
# "publish", "service".
logging.selectors: ["*"]
