It seems like $tempFile defined by $storage->createFile('sf_events_export.csv', $tempFolder) on line 84 can also be of type null; however, TYPO3\CMS\Core\Resource\ResourceStorage::dumpFileContents() does only seem to accept object<TYPO3\CMS\Core\Resource\FileInterface>, maybe add an additional type check?
