[Koha] Elasticsearch again

[Tom Hanstra]

Earlier testing of Koha 19.11.03 with Elasticsearch 7 and 6 both gave
errors. There was some suspicion that perhaps Elasticsearch had to be
rolled back to V5.

So, I did that today, as well as upgrading Koha to 19.11.04. And I am
getting a new error. Basically, now, it looks like there might be a
configuration error somewhere?

Here is my current error when trying to index:

PERL5LIB=/usr/share/koha/lib:/usr/local/lib:/usr/local/share/perl5
./bin/search_tools/rebuild_elasticsearch.pl -d -v -p 4

=> {},'method' => 'PUT'},'status_code' => 400}

FWIW, Koha knows what the indices should be but also seems to know that
they do not yet exist:

Nodes: localhost:9200 | Status: running | Indices:
koha_london_test_20_biblios (count: -1), koha_london_test_20_authorities
(count: -1)

Anyone seen this type of error or have ideas on what might be going on with
this particular issue?

Thanks,
Tom
