Then you need to enable stream caching.

I don't think we can read it twice if camel don't cache it.

By default the message contains whatever it was before the "step" in
the Camel route failed.
However you can use the .useOriginalMessage() option on the Dead
Letter Channel to tell it to use the original input message instead.
