Loading ads with Zaraz cause error

Hi,

I tried Zaraz to load Google Analytics 4 and it works perfectly!
Now I want to load my ads (not Adsense). I tried to add the js files in custom HTML.
The files look like this:
<script async src='https://myadfile.js'></script>

Now the ad on the page returns an error because the ad depends on myadfile.js and didn’t find it.
The ad on the page looks like this:

<script>  
cnx.cmd.push(function(){cnx({playerId:"0000000"}).render();});</script>

The error: cnx is not defined. (because the cnx is defined in the myadfile.js which is loaded by Zaraz).

So how to solve this issue?

Regards,

Why not set your Custom HTML to

<script async src='https://myadfile.js'></script>
<script>cnx.cmd.push(function(){cnx({playerId:"0000000"}).render();});</script>

@yoav_zaraz I make it as you said. Now ads are showing, but the page speed degraded from 99 to 60 !!!
I was doing lazy load (load ads when users interact with the page), but after enabling Zaraz, I disabled lazy loading it and run Zaraz only to see what it will do.

I thought Zaraz will improve the CWV INP and page performance, but it looks like it’s not suitable.

Zaraz does not and cannot optimize Custom HTML snippets. See FAQ · Cloudflare Zaraz docs for more information
