get_queried_object return false when executed in parse_query hook

[fliespl]

When this function is executed in parse_query hook (i.e. woocommerce-perfect-seo-url) on author page ( /author/XXX/ ) it results with this notice.

#13 E_NOTICE: Trying to get property 'ID' of non-object

It's because 'author_name' is not converted into 'author' field in parse_query.

It's only used to mark page as "is_author".

			if ( '' != $qv['author_name'] ) {
				$this->is_author = true;
			}

And get_queried_object relies on 'author' variable.

		} elseif ( $this->is_author ) {
			$this->queried_object_id = (int) $this->get( 'author' );
			$this->queried_object    = get_userdata( $this->queried_object_id );
		}

Thanks for the ticket, we're already tracking this issue in #29660.

I have seen this thread and I am pretty sure this issue is not handled there.

Thread you mention is about usage of function that might return null.

Issue described here is about proper population of object information in get_queried_object and get_queried_object_id functions.

I am re-opening it as I have a feeling it's totally different issue.
