I have run into some unique error messages using the same scripting for nearly 200 pages. The publishing pages are highly customized, but this error seems unrelated b/c we are transforming to HTML, and the process generally ignores highly customized web parts or generates a more functional error message. Has anyone run into something similar and can share their approach to resolving and moving forward? I tried posting as many details as possible.

$sp13Conn = Connect-PnPOnline https://companysitesp2013 -TransformationOnPrem -ReturnConnection
$spOnlineConn = Connect-PnPOnline https://SPOcompanysite -Interactive -ReturnConnection
Connections are functioning as expected. I connect to both SP2013 and SPO.

I am receiving an error message "the cmdlet "Export-PnPPageMapping" has encountered an error, and the ServerErrorTraceCorrelationId "20c89fa0-5e65-d0b4-5480-7908f400d98e" has been generated as a unique identifier for this error."

The "Get-PnPException" cmdlet was used to retrieve more information about the error. However, in this case, the error message seems incomplete, and no specific information was provided about the error that I have found useful.

I looked into the possibility that the problem was due to the fact the site is a subsite. I received the same error message.
