fscrawler 2.3 with elasticsearch 5.5 getting error string index out of range

Question

I have ElasticSearch 5.5 with x-pack working without any issue.

But while I trying use fscrawler 2.3 on a folder I get this error

WARN  [f.p.e.c.f.FsCrawlerImpl]
Error while crawling c:/tmp/es: String index out of range: -1

What am I doing wrong?

Answer 1

Try to use backslashes in the url of the _settings.json - like "C:\\tmp\\es"
