Hi, When deploying functionbeat, I can get it to successfully deploy to Lambda. However, when looking at logs I get the following error-

fork/exec /var/task/functionbeat: exec format error: PathError null

````auto
functionbeat.provider.aws.deploy_bucket: "<bucket>"
functionbeat.provider.aws.functions:
  - name: eventlogsfunctionbeat
    enabled: true
    type: kinesis
    description: "lambda function for event log kinesis"
    triggers:
      - event_source_arn: arn:aws:kinesis:eu-west-1:<account>:stream/OrganizationCloudTrailStream
output.elasticsearch:
  hosts: ["https://<url>.eu-west-1.aws.found.io:9243"]
  username: 'elastic'
  password: '<password>'
  index: "functionbeat"

setup.kibana:
  host: "https://<url>.eu-west-1.aws.found.io:9243"
  username: 'elastic'
  password: '<password>'

setup.template.name: "functionbeat"
setup.template.pattern: "functionbeat-*"
setup.template.enabled: false```

The lambda function works when using Cloudwatch as the input, but doesn't when using kinesis
