Magento 2.x Elasticsearch Category Products Not Showing

Question

I tried to upgrade my Magento 2.3.5 install to Magento 2.4.0, but am unable to get category pages to display products. Everything is in Docker, so I am using Elasticsearch 7.6 and have specified elasticsearch7 for catalog/search/engine. The test from the Magento admin is successful. The category pages were working with 2.3.5 so I am assuming this is something related to the switch to Elasticsearch. I've looked at various upgrade guides without much luck as reindexing isn't fixing it for me.

The search works and returns products, as does loading a product detail page directly, and viewing the products in the Admin, however viewing any category page just shows:

We can't find products matching the selection.

Things I've tried:

1. Updated to Magento 2.4 using composer (via Docker) and then ran magento setup:upgrade and cleared cache.

2. Verified that products are enabled, visible, in stock, have quantity, and are assigned to category

3. Disabled all non-Magento modules, deleted ./generated/code, ./var/view_preprocessed, changed theme to Magento Blank.

4. Cleared Cache / Reindexed

5. Deleted Elasticsearch indices, reindexed, and checked using curl

I noticed that there is no "category" index being created but not sure if there should be...

6. Enabled and disabled Flat Categories

7. Deleted and re-imported all Products

After deleting and re-importing the products I reindexed, cleared cache, regenerated thumbnails, etc. but still seeing the same behavior.

Edit - I deleted the database and reinstalled from scratch, imported products/categories, cleared cache, etc and the category pages are still not working. Can someone with a working install let me know how many indices are created in Elasticsearch? Can someone provide a same product import CSV that is working correctly for me to test?

Answer 1

I located an exception in ./magento/var/log/exception.log that showed an issue with the configuration of a custom attribute. The attribute was set to a type of text for the attribute custom_attribute in the eav_attribute table, but is_filterable set to 1 in the catalog_eav_attribute table. Setting this value to to 0 and reindexing/clearing cache allowed the category pages to load as expected.

JOIN eav_attribute ea
  ON ea.attribute_id = cea.attribute_id 
  AND backend_type IN ('text')
WHERE 
  cea.is_filterable = 1 OR cea.is_filterable_in_search = 1

Set is_filterable to 0 to allow category pages to load.

Answer 2

Please run following command and then try:

service elasticsearch start

Answer 3

In my case,
The issue is happened because of 2 attribute “jajuma_product_latitude” and “jajuma_product_longitude“ don’t show in store view.
I’ve change 2 parameters of this 2 attributes and run this command:

php bin/magento c:f && php bin/magento indexer:reindex

And the products are show as expected in categories.

Hope it help.

Answer 4

I got similar issue (no products listing) and solved by following command:

php bin/magento index:reindex
