dockergento amasty elasticsearch can't find products

Question

I thought it was a problem of elasticsearch version, updated it still same error, tried reindexes and so on... on admin page everything seems to be fine anchor->yes and so on. used that link looked like a fix and solution but after modifying my code and saving new 'elasticsearch' from admin I had nginx 502 error (on a specific page where the products must be). any suggestion? I also used some queries,

CREATE OR REPLACE VIEW inventory_stock_1 AS select distinct legacy_stock_status.product_id AS product_id, legacy_stock_status.website_id AS website_id, legacy_stock_status.stock_id AS stock_id, legacy_stock_status.qty AS quantity, legacy_stock_status.stock_status AS is_salable, product.sku AS sku from ( cataloginventory_stock_status legacy_stock_status join catalog_product_entity product on (( legacy_stock_status.product_id = product.entity_id )));

multiple reindexes. still nothing

-setted up hp project with clean database,added product for testing - setted up elastic Search, -on blank theme everything seems to be fine -changed theme to hp and product was not visible anymore -started debugging collection -updated elasticSearch to 1.8.1 -saw product on home page(inserted catalog product list widget before) , then when I clicked on it found error ->Array to string conversion in /var/www/html/app/design/frontend/devall/hp/Magento_Theme/templates/html/header-links.phtml on line 14. https://i.imgur.com/Wp8tx1r.png https://i.imgur.com/azjlaTB.png -installed hp on clean database once again to see if elasticSearch update was the thing. -found out that category was not showing products anyway... -had errors on product page even with mysql search, checked same on dev,there was not the same errors. -maybe I'll use databaseDump again to check if it removes that product page errors and then debug Our themes collection
