Yesterday I told you, that you can select the entities which are searched by default on the Shopware administration dashboard. That was a chance find, while debugging while the search doesn’t work at all.

If you are running elastic/open search all entities which are searchable need an Indexer, a few hints how to do it, because I can’t find any documentation for it:

<service id="Shopware\Elasticsearch\Admin\Indexer\ProductAdminSearchIndexer">
    <argument type="service" id="Doctrine\DBAL\Connection"/>
    <argument type="service" id="Shopware\Core\Framework\DataAbstractionLayer\Dbal\Common\IteratorFactory" />
    <argument type="service" id="product.repository"/>
    <argument>%elasticsearch.indexing_batch_size%</argument>

    <tag name="shopware.elastic.admin-searcher-index" key="product"/>
</service>

<?php declare(strict_types=1);

namespace Shopware\Elasticsearch\Admin\Indexer;

#[Package('system-settings')]
final class ProductAdminSearchIndexer extends AbstractAdminIndexer
{
    // [...]
}

Error on the browser console

If you don’t implement this indexer and you try to use it (e.g. on the dashboard) you get an error like this:

{
    "errors": [
        {
            "status": "500",
            "code": "ELASTICSEARCH_INDEXING",
            "title": "Internal Server Error",
            "detail": "Following errors occurred while indexing: \n",
            "meta": {
                "parameters": []
            }
        }
    ]
}

Not very helpful, because the „real“ error is eaten somewhere.

Looking into the log (var/log/prod-<date>.log)

[2023-12-15T11:53:47.554940+00:00] request.CRITICAL: 
    Uncaught PHP Exception Shopware\Elasticsearch\Exception\ElasticsearchIndexingException:
        "Following errors occurred while indexing:  " 
        at /var/www/vendor/shopware/elasticsearch/Admin/AdminSearchRegistry.php line 17
        {"exception":"[object] (Shopware\\Elasticsearch\\Exception\\ElasticsearchIndexingException(code: 0): Following errors occurred while indexing: \n at /var/www/vendor/shopware/elasticsearch/Admin/AdminSearchRegistry.php:175)"} []

Okay, a file and a line

public function getIndexer(string $name): AbstractAdminIndexer
{
    $indexer = $this->indexer[$name] ?? null;
    if ($indexer) {
        return $indexer;
    }
    // line 175 - how unexpected.
   throw new ElasticsearchIndexingException([\sprintf('Indexer for name %s not found', $name)]);
}

So in theory we should get this error and the indexer name, but it gets lost somewhere. So the old way

var_dump() and die() debugging

Although we know how xdebug works, there are times were „the good ol‘ way“ brings as faster results. And especially if I’m running on the shopware backend, I „only“ disturb our customer, not the customer’s customer. So I added a var_dump($name); die(); and got an indexer name out.

Easy fix

If you want an easy fix, look at the post from yesterday and just remove the indexer from the „all“ list.

Better fix

Implement an elastic search indexer or tell the plugin vendor to do it.
