I try to import data from couchDb using Logstash (7.5.0) to Elasticsearch (7.5.0).  
When defining a Mapping in ES, I select "dynamic" = "strict"  
and in my elasticsearch output plugin I have:  
document\_id =\> "%{[@metadata][\_id]}"  
action =\> "update"  
doc\_as\_upsert =\> "true".  
Yet, ES complains that this is not in the Mapping and that dynamic mapping should be disabled.  
It works when I select "dynamic":"false" but with this setting can I be sure that Logstash will always try to upsert data and not create multiple duplicates? As I understand, with "dynamic":"false" in the Mapping definition, the field "doc\_as\_upsert" is ignored when inserting into the database. Does Logstash only perform upserting then? (Merge not create a copy).
