Metricbeat unable to start

Anyone ever have issues getting the metricbeat service to start on a 2012 R2 server where the filebeat log says Exiting: can not convert 'object' into 'string' accessing '0.hosts.0' (source:'C:\ProgramData\Elastic\Beats\metricbeat\modules.d\auto-auth.yml')

Hi,

would you mind sharing this file (auto-auth.yml)? Have you modified it?

I know this is Windows, but can you try forward slashes instead?

C:/ProgramData/…

It has been customized. It happens on any of the module.d files in there. I can disable the first one and it will fail at the next one in line.

Here is the contents of the auto-actions.yml file it fails on first.

# Module: sql
# Docs: https://www.elastic.co/guide/en/beats/metricbeat/7.8/metricbeat-module-sql.html
# PS

- module: sql
  metricsets:
    - query
  period: 1m
  hosts: ["Removed Specific Information"]

  driver: "mysql"
  sql_query: 'Query Removed'
  sql_response_format: table

One thing I noticed with this one machine facing the issue, when opening this file in Notepad there is no format to the file, even with Word Wrap on. If I open this file on my personal machine I see the formatting correctly.

I can take the file from this non-working machine and put it in a different machine and it works fine. Take a working machine's file and put it in the non-working machine and it fails to start the service. I have also attempted to uninstall/reinstall the Metricbeat agent.

If it helps, here is the log file.
