I think we need to add to condition if html contain sting then do that stuff, otherwise getting error

Could you please comment on what causes you to suggest this change? Is there an error or a warning? For which specific page would the transport of an HTML event when outputting a Magento page be blank?

Thanks. Could you upgrade to the latest versions of NextGenImages and WebP2 to see if this fixes your issue? It would be a bit silly to troubleshoot issues that are already fixed.
