Problem with ESI Shortcode

Hi,

I need few elements to have very less Cache time and so I added them as Shortcodes with ESI as given below.

<?php echo do_shortcode('[esi asx_price ttl="30"]'); ?>

It’s working fine but after few days, these Shortcodes not returning anything and just empty. Please see below for rendered output with blank data.

<h4><!-- lscwp esi-shortcode --><!-- Block generated by LiteSpeed Cache 5.3.3 on 2023-04-25 16:42:06 --><!-- lscwp esi-shortcode esi end --></h4>

But when I flush LiteSpeed Cache, it starts working again and an example of the rendered output of Shortcode is given below.

<h4><!-- lscwp esi-shortcode --><a href="https://www.example.com" target="_blank">ASX:  $0.105 <span class="green">0%</span></a><!-- Block generated by LiteSpeed Cache 5.3.3 on 2023-04-26 10:23:22 --><!-- lscwp esi-shortcode esi end --></h4>

This issue is appearing in all my sites and can you let me know what’s wrong with this and why only these Shortcodes rendering blank output after a few days when I manually flush LiteSpeed Cache?
