UPDATE:
The problem is not with the filename
Issue was with Metadata (Content-Type):

  • first log file (problem):
    Content-Type application/octet-stream
  • second (correctly processed):
    Content-Type application/json

filebeat.yml - pretty simple:

filebeat.inputs:
- type: aws-s3
  queue_url: https://sqs.xxxxxxxx
  access_key_id: xxxx
  secret_access_key: xxxx

output.console:
  pretty: true

Without file_selectors or any regexes processed settings
