If you download the module via git, e.g. for local testing or working on d.o issues, the module doesn't work. This happens because the module checks Composer to see what release is installed:
namespace Drupal\search_api_solr\Plugin\search_api\backend;
use Composer\InstalledVersions;
..
class SearchApiSolrBackend extends BackendPluginBase implements SolrBackendInterface, PluginFormInterface {
..
public function getPreferredSchemaVersion(): string {
$installed_version = InstalledVersions::getPrettyVersion('drupal/search_api_solr');
if (!preg_match('/^\d+\.\d+\.\d+$/', $installed_version, $matches)) {
return self::SEARCH_API_SOLR_MIN_SCHEMA_VERSION;
}
return $installed_version;
}
If you download the module via git, and manually download the dependencies via composer, this code won't work as "drupal/search_api_solr" is not defined in Composer's index.

FWIW wrapping the code in a try-catch block works around the issue, e.g:
try {
$installed_version = InstalledVersions::getPrettyVersion('drupal/search_api_solr');
}
catch (\Exception $e) {
return self::SEARCH_API_SOLR_MIN_SCHEMA_VERSION;
}
