Elasticsearch7 returns string but not array for the category page.

[sohaibgondal]

When I tried to load my category page, the following error showing..

TypeError: Return value of Magento\Elasticsearch7\Model\Client\Elasticsearch::query() must be of the type array, string returned /hostname.local/app/code/Magento/Elasticsearch7/Model/Client/Elasticsearch.php:367

Versions details

• Mac OS Big sure 11.2.x
• MAMP Pro 6.3.1
• Magento 2.4.2
• Elasticsearch 7.12.0 (installed recently using Homebrew)

This issue is reported here before but there is no help at all.

I updated the Store->Configuration -> Catalog -> Catalog -> catalogSearch area in admin and the Test button returns Successfull.

Any kind of help will be appreciated..
