Sharer prefetching issue

[akhilrajrsahithi]

Hi dear,
when i click share button from my website(url is provide below), it won't show the image in preview ,
http://appsoftheyear.000webhostapp.com/viewimage.php?im=5883ea8cbbc25.jpeg&userid=1283058238404170
I tried to debug url by sharing debugger it shows the following warning

Inferred Property

The 'og:url' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property
The provided 'og:image' properties are not yet available because new images are processed asynchronously. To ensure shares of new URLs include an image, specify the dimensions using 'og:image:width' and 'og:image:height' tags. Learn

this the code i used to set meta tag

_
<title>appsoftheyear</title>

<?php

	parse_str($_SERVER['QUERY_STRING']);
	echo '<meta property="og:url" ';
	echo ' content="https://appsoftheyear.000webhostapp.com/viewimage.php?im='.$im.'&userid='.$userid.'" ';
	echo ' />';
	
	 
	?>
	
	<meta property="og:type"          content="website" />
	<?php
	
	parse_str($_SERVER['QUERY_STRING']);
	echo '<meta property="og:image"';
	echo ' content="https://appsoftheyear.000webhostapp.com/'.$im.'" ';
	echo ' />';
	 
	?>
	<meta property="og:image:type"    content="image/jpeg" />
	<meta property="og:image:width"  content="800" />
	<meta property="og:image:height" content="420" />
