what config did u added?

[kkai24]

@Matthew2015 I added a configuration called recordCrossOriginIframes, and then I used postmessage to publish child monitoring messages and start recording them. The next parent monitoring message also started recording. Therefore, the method I adopted is that both parent and child components require a record.

Does your iframe site also include rrweb? Either the containing document can see into the iframe via the DOM (iframe.contentDocument etc.) or else for e.g. a 3rd party site, they both need to load up rrweb (I haven't ever done this personally)

I have tried recordCrossOriginIframes : true , its not record iframes content i saw blank white space instead of iframe content , i m still confused how to record cross-origin iframes ?

Also its helpful if you let me know how you use postMessage API with this config
