$parentPlugin is of type object<ApacheSolrForTypo3\Solr\Plugin\CommandPluginBase>, but the property $parentPlugin was declared to be of type object<ApacheSolrForTypo3\Solr\Plugin\Results\Results>. Are you sure that you always receive this specific sub-class here, or does it make sense to add an instanceof check?

It seems like $parentPlugin->typoScriptConfiguration of type object<ApacheSolrForTypo3\Solr\System\Configuration\TypoScriptConfiguration> is incompatible with the declared type array of property $configuration.
