It seems like \Netdudes\DataSourceryBundle\UQL\Lexer::matchToken($string, 0) targeting Netdudes\DataSourceryBundle\UQL\Lexer::matchToken() can also be of type array<string,?,{"match":"string","token":"?"}>; however, PHPUnit\Framework\Assert::assertFalse() does only seem to accept boolean, maybe add an additional type check?
