This error will be logged when Elasticsearch tries to index data that is an object, into a field that is not [mapped](https://www.elastic.co/guide/en/elasticsearch/reference/current/object.html) as one. Or in reverse, if you try to index something that isn't an object into a field that is mapped as one.

Common sources of this error are from data being sent from Filebeat or Logstash. This thread has two good examples - [Logstash Errors mapper\_parsing\_exception vs illegal\_argument\_exception](https://discuss.elastic.co/t/logstash-errors-mapper-parsing-exception-vs-illegal-argument-exception/236783)

You will need to check the mapping for the related index, and compare that to the value that is being sent to Elasticsearch for indexing. If you are using Filebeat/Logstash, you may need to adjust any processing of the events that they are doing, and [this post](https://discuss.elastic.co/t/problem-logstash-outputs-elasticsearch-could-not-index-event-to-elasticsearch-wazuh-alerts-3-x-2020-05-30/235038/6) has a good example of what you can do.

This is the sort of error from Beats that you may run into that relates to this topic;  
`{\"type\":\"mapper_parsing_exception\",\"reason\":\"object mapping for [X] tried to parse field [X] as object, but found a concrete value\"}, dropping event!`
