[Peter Zhao]

Hi, I installed a koha and used UNIMARC, zebra index works well but the elastic index cannot work, when I do "sudo koha-elasticsearch --rebuild -b -v library", it shows errors.
Koha version: 19.05.04.000
OS version ('uname -a'): Linux koha 4.15.0-65-generic #74-Ubuntu SMP Tue Sep 17 17:06:04 UTC 2019 x86_64
Perl interpreter: /usr/bin/perl
Perl version: 5.026001
-------
I'v  got the following error message .  How to fix this problem?  
Peter
