Content type detection for rest requests is deprecated with lastest ES and FSCrawler

Elastic Stack Elasticsearch
1

Getting:

[299 Elasticsearch-5.4.1-2cfe0df Content type detection for rest requests is deprecated. Specify the content type using the [Content-Type] header

This occurs are startup of FSCrawler.

Thought this was resolved with lastest:
Elasticsearch: 5.4.1
FSCrawler: 2.2

Any thoughts ?

This is fixed in FSCrawler 2.3. Try the latest SNAPSHOT. Link is available in the README.

great, thx.

I will probably wait for a stable zip package for 2.3

TBH the latest 2.3-SNAP is more stable than the 2.2 version... :slight_smile:

I hope I can release it anytime soon though.

Ok, thx.

Going with
fscrawler-2.3-20170602.114150-43.zip Fri Jun 02 11:41:54 UTC 2017

Very interesting. Another user reported something like that. Ok can you open an issue in FSCrawler project. I'll check and fix that.

Thanks !
