wireTap issue: Exchange is empty while copy defaults to true
Hello,
Using Camel 2.9.1, consider the routeBuilder (in DSL)
The routing goes fine to the target FTP, but does not write the test.txt
file. For the "direct:tap" route, I am getting the warning:
According to tracing, the endpoint .to("file://test.txt") exists and is
created, but it seems that somehowe, the Exchange is empty?
(Exchange[null]). This is strange, as the default behaviour would be to copy
the in part of the exchange message.
Does anyone know why this is empty? How can I correct this?

Yes that could be an option.

Is this a scenario where the WireTap's onPrepareRef might be helpful to
capture the needed information from the tapped Exchange before its parent
message is consumed?

You use local work directory with the FTP endpoint which means the
file is stored temporary in that directly.
And when the message is done being processed the file is deleted.
So when you tap the message, you only tap a java.io.File handle to
that temporary file.
