need opensearch bulkapi to send logs to aws opensearch

[quinyx-max]

hi
i tried to use the elasticsearch_bulk_api.lua in a new output file called opensearch.cfg. but i get http 400 in the logs. user/pass/endpoint is configured correctly so the only thing i can think of is that the opensearch_1,3 from aws does not support the elasticsearch_bulk_api.lua format somehow.
one more thing is that as soon as the new output added to the hindsight, the current setup with elasticsearch (different output.cfg file) gets disrrupted
