Sitemap custom type post

Hi,

I try to understand the process of the sitemap inside Yoast.

I’ve got a sitemap.xml :
https://paul-fsm.net/sitemap_index.xml

My custom post type are declared with public = true.

I don’t find my custom type post inside the main XML.
They are done when i go on :
https://paul-fsm.net/ecole-sitemap.xml or https://paul-fsm.net/?sitemap=ecole
https://paul-fsm.net/emploi-sitemap.xml
https://paul-fsm.net/diplome-sitemap.xml
…

For information : I use your htaccess instructions :
https://kb.yoast.com/kb/xml-sitemaps-apache/

I use Yoast Free edition.

• I already try to disabled / enabled sitemap inside yoast : Nothing change.
• I already try to desactivate / reactivate yoast plugin : Nothing change
• I already try to empty the cache with W3 Cache : Nothing change
• I already try to desactivate / reactivate W3 cache plugin : Nothing change again.

I check your code and i put some line in commentary :

Inside : wordpress-seo/inc/sitemaps/class-sitemap.php (line 224 & 226)

public function redirect( $query ) {

		if ( ! $query->is_main_query() ) {
			return;
		}

		$xsl = get_query_var( 'xsl' );

		if ( ! empty( $xsl ) ) {
			$this->xsl_output( $xsl );
			$this->sitemap_close();

			return;
		}

		$type = get_query_var( 'sitemap' );

		if ( empty( $type ) ) {
			return;
		}

		$this->set_n( get_query_var( 'sitemap_n' ) );

		//if ( ! $this->get_sitemap_from_cache( $type, $this->current_page ) ) {
			$this->build_sitemap( $type );
		//}

		if ( $this->bad_sitemap ) {
			$query->set_404();
			status_header( 404 );

			return;
		}

		$this->output();
		$this->sitemap_close();
	}

And when i do that : nothing change when i check the normal URL :
https://paul-fsm.net/sitemap_index.xml

BUT when i add a parameter : like that :
https://paul-fsm.net/sitemap_index.xml?toto=1

The sitemap update with my custom post type !
AND I DON’T UNDERSTAND WHY !

I try everything : Change my priority init hook for my custom post type, review all my code … don’t working !
