"Error: Call to a member function setName() on null" - on partial word search

[mazurekiza]

Preconditions

Magento Version : 2.4.7-p1

ElasticSuite Version : 2.11.8.3

Environment : developer and production mode

Steps to reproduce

1. Set configuration for search fuzziness and phonetic to No.
   
2. On search, try to search by part of the word. Example: full word is "jadalnia", part of word to search is "jada".
   

Expected result

1. Search result page with info "No exact results found for: '%1'. The displayed items are the closest matches." should be rendered.

Actual result

1. Error is displayed/logged into the file:
   Error: Call to a member function setName() on null in /var/www/html/vendor/smile/elasticsuite/src/module-elasticsuite-core/Search/Request/Query/Fulltext/QueryBuilder.php:88

Additional info

In class vendor/smile/elasticsuite/src/module-elasticsuite-core/Search/Request/Query/Fulltext/QueryBuilder.php:87 the $query variable is set as null because \Smile\ElasticsuiteCore\Search\Request\Query\Fulltext\QueryBuilder::getSpellcheckedQuery can and it returns null in case fuzzy and phonetic search are disabled.
