WordPress add_rewrite_rule 404 error

I am adding rewrite_rules for my custom project.

I was able to make them work till some extent, but have some difficulties.

Here's what i have tried out so far

public function add_query_vars($vars) {
$vars[] = 'gallery';
$vars[] = 'project';
$vars[] = 'palbum';
return $vars;
public function add_endpoint() {

Here project is parent and palbum are all its child.

It seems to work properly at

(These page is to show single album)

But it gives me 404 error at

(These page is to show all albums which the project is parent of)

Any clue why?

public function add_endpoint() {
     * Matches:
