This looks exactly like the problem caused by ES clients not wanting to 
talk to some versions of ES server. David posted this to the koha-devel 
list in another thread about the same problem:


which ES perl client is installed?

the newest version that still works with ES7 (which we are using) is

https://metacpan.org/release/EZIMUEL/Search-Elasticsearch-7.717/view/lib/Search/Elasticsearch.pm

check currently installed version
`perl -MSearch::Elasticsearch\ 9999
Search::Elasticsearch version 9999 required--this is only version 7.717.`

if necessary, downgrade
`cpanm Search::Elasticsearch~"< 8.00"`


For us, downgrading "solved" the ES problems with newer Debians.
