I am seeing an error: > Rejecting mapping update to [logstash-INDEXNAME-2021.08.03] as the final mapping would have more than 1 type: [\_doc, doc] I suspect this is due to me switching my template from using doc to using \_doc, but I deleted the index in question and recreated it to no effect. Furthermore I have a test system with an index template that uses \_doc that is not having the same issue. So I do not understand why it is happening in the one system but not the other, and how I can rectify the error. ---

I guess I should be using document\_type in the ES output, or "doc" in the template? > > > I asked this previously \[on the forum\](https://discuss.elastic.co/t/elasticsear…ch-doc-type-deprecation-doc-vs-doc/139799) but it didn't seem to draw any attention. > > The \[advice in the doctype deprecation notes\](https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html#\_schedule\_for\_removal\_of\_mapping\_types) is to use a document type of \`\_doc\` in 6.x to prepare for type removal.

But that does not explain why it works on my test system without issue... ---

Neither the input nor output are specifying the type. For some reason the index template is not applying in my test environment, but is in my production environment. ---

Have you tried removing the type from the template definition? ---

That is basically what I did, I created the template with include\_type\_name=false. The only fix I can see is to use include\_type\_name=true and specify the type as "doc". This is Logstash/Elastic 6.8 btw. ---
