Adobe Experience Cloud Debugger and s.pageType
I am doing some verification work for a client site using the Adobe Experience Cloud Debugger tool.
I think I have encountered a bug where s.pageType is not shown in the Debugger.
One of the pages we track is the 404 page with s.pageType = "errorPage". However, s.pageType is not turning up in the Debugger tool. The following is the recording in the debugger tool:

nah, just censoring out client information)
The following is a partial screenshot of the raw request made:
This can be replicated with any page set with s.pageType = "errorPage" in a page load rule in Adobe Launch.
