I'm using logstash to store events/logs in to google cloud storage via the logstash.
Using this plugin https://www.elastic.co/guide/en/logstash/current/plugins-outputs-google_cloud_storage.html
However recently I discovered I've uploaded wrong json_key_file in one of my landscapes, and for days (weeks) logstash has been running and not logging any error that it cannot store the files.
I've verified the issue, and it seems it's not logging any error at all.
I tried setting the log4j2 level to debug and forward the app output to stdout, however the only logs I can see it the incoming events the following message, like it works as expected:
Uploading file to <my-bucket>/events-_event-logstash1-7b747f9779-zttg9_2019-10-21T13:00.part000.f9b790ff-c080-49b3-b579-380855ff1a72.log
However it is provided with invalid credentials for gcp and the file is never uploaded.
Is it something that I'm misconfiguring, or is it a bug?
