Filebeat 7.12 output.file not working

Hi,

Please advise why this output.file isn't working. I'm on windows and trying to get the events filebeat is sending to my logstash. I don't have access much on the logstash logs and stuff so i'm trying to output the events to a file and check from there. When i start the filebeat service, the Windows couldn't start the service. Below is the config.

output.file:
enabled: true
path: "C:\Filebeat_7.12"
filename: filebeat

What error is the Windows Service (Events) showing? Are those the only configurations you have changed and all the rest are default in the filbeat.yml file?
