Why does attachment_url_to_postid return 0 when given value through variable in WordPress functions.php?

I’m trying to get post id of image and then get specific size of image.
If I give hardcode single image url then it works fine but if I give url through variable then it returns 0.
It is strange behaviour

here is function

function get_image_id_and_size($image_url) 
{
    
    //return $image_url;
    
    $image_id = attachment_url_to_postid($image_url);
    
    return $image_id;
    
    $image_large = wp_get_attachment_image_src($image_id, 'large');
    
    
    return $image_large[0];
    
}

and here is javascript code

    var picture = document.querySelectorAll(".active");
for (var i = 0; i < picture.length; i++)
    {
        var src = picture[i].src;
        if (typeof src !== 'undefined')
        {
            var res;
            if (src.includes('bedbase') && src.includes('12in_'))
            {
                        
                var imgurl = src.split('12in_');
                var imgres = imgurl[1].split('-');
                var orgurl = imgurl[0] + "12in_" + currentcolor + ".png";
                                
                //console.log(orgurl);
                res = <?php echo get_image_id_and_size(orgurl); ?>;
                console.log(res);
                //picture[i].src = res;
                        
            }
        }
    }
