What version of fscrawler is compatible with elasticsearch 6.3

i installed many version of fscrawler but no one works with es 6.3 (when tryin --loop 1 commande it throws compatibility error) so what version of fscrawler is compatible with elasticsearch 6.3

I think that the 2.6 version should be compatible.
What is exactly the error message? Could you run it with the --trace option?
