Hello!
While trying to download a pdf full of charts and tables (and massive queries that can take up to 40 secs for now).
We are getting this error:
Waiting for selector `:root:not(.ultimate-pdf-is-not-ready)` failed: Waiting failed: 30000ms exceeded 
I'll leave the stack below if it helps.

Since the charts and the DA are all async, on the onReady we are setting the client action WaitUntilReadyBeforeCapturing and we have the webblocks triggering events outside to the PDF screen so that we can evaluate if we can trigger the IsReadyForCapture (all of this have been tested and works, atleast on the preview).
Also on the action ScreenToPDF_OnInitialize the we have on the onInitialize of the PDF screen, we've set both OpenInBrowser and Preview to False (don't know if this makes any difference on the error or not)

The timeout defined for the ServerAction that calls the PDF export action, is set to 500 seconds, and so is the module (in order to check if that was the problem or not)


Here's the stack:
