Fatal error: Declaration of Drupal\search_api_solr\Solarium\Autocomplete\RequestBuilder::build(Solarium\Core\Query\AbstractQuery $query): Solarium\Core\Client\Request must be compatible with Solarium\Core\Query\AbstractRequestBuilder::build(Solarium\Core\Query\QueryInterface|Solarium\Core\Query\AbstractQuery $query): Solarium\Core\Client\Request in /var/www/html/web/modules/contrib/search_api_solr/src/Solarium/Autocomplete/RequestBuilder.php on line 23"</h2>
Pretty straightforward from the error message: RequestBuilder::build $query variable type doesn't match AbstractRequestBuilder::build one that defines it as QueryInterface|AbstractQuery.
On Solarium\Core\Query\AbstractRequestBuilder update
public function build(AbstractQuery $query): Request
to public function build(QueryInterface|AbstractQuery $query): Request (and method documentation.
Needs work
4.0

Thanks, but it is fixed in the dev branch on github already.
Automatically closed - issue fixed for 2 weeks with no activity.
I am also facing this issue, currently using 4.3.1 version of search_api_solr. Can you tell which version I can upgrade to for fixing this issue?
