Javascript code not executing when running PHP script via cron job.

I have a PHP script that includes JavaScript code. When I call the PHP script manually on my browser, the JavaScript code executes successfully and performs the expected actions. However, when the same PHP script is executed via a cron job, the JavaScript code is printed as plain text instead of being executed. I am running on a Linux server (HOSTINGER). I run the same code on a Windows server and it works perfectly. 

<pre lang="PHP"><pre><?php
session_start();

include "sqlserver.php";


?>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
	

	
	async function trigger_test_function() {
			
		
		var output="Success";
		var temp_txid="a6s5df46asdf4";
					
			 $.ajax({
			 
        type:"POST",
		url:'update_trxid.php',
		data: {trxid:output,temp_txid:temp_txid},
		success: function(response){
			        console.log(response);
		   }
		 });
			
});
    } catch(error) {
		
 console.log(error);
				} 
	}
		
		
		trigger_test_function();
</script>

I am running the same code on a Windows server and it works perfectly.
