Bug introduced by
It seems like $crawler defined by $this->client->request('...lf::URL_SUBJECTS, $id)) on line 51 can be null; however, Defr\Justice::extractDetailUrlFromCrawler() does not accept null, maybe add an additional type check?

Unless you are absolutely sure that the expression can never be null because of other conditions, we strongly recommend to add an additional type check to your code:

/** @return stdClass|null */
function mayReturnNull() { }

function doesNotAcceptNull(stdClass $x) { }

// With potential error.
function withoutCheck() {
    $x = mayReturnNull();
    doesNotAcceptNull($x); // Potential error here.
}

// Safe - Alternative 1
function withCheck1() {
    $x = mayReturnNull();
    if ( ! $x instanceof stdClass) {
        throw new \LogicException('$x must be defined.');
    }
    doesNotAcceptNull($x);
}

// Safe - Alternative 2
function withCheck2() {
    $x = mayReturnNull();
    if ($x instanceof stdClass) {
        doesNotAcceptNull($x);
    }
}
