System_api_version [7] is not supported by system_id

Hi, i get the following error when i am trying to send monitoring data from metricbeat to elasticsearch.

ERROR pipeline/output.go:121 Failed to publish events: 400 Bad Request: {"error":{"root_ cause":[{"type":"illegal_argument_exception","reason":"system_api_version [7] is not supported by system_id [beats]"}],"typ e":"illegal_argument_exception","reason":"system_api_version [7] is not supported by system_id [beats]"},"status":400}

what could be the problem ?

i am running
Filebeat 7.2
Elastic 6.7.1
Logshash 7.2


Hello, thanks for your post. I suspect the issue is logstash 7.2 commicating with elasticsearch 6.7.1. I've seen similar issues with newer versions of beats talking to an older version of logstash.

It may be worthwhile to review our support matrix to ensure you're running compatible versions of Elastic Stack components.

Please let us know if you have questions.
