The Api node on Oslo-messaging sends a request to the policy node asking for say policy alpha. The policy node raises an exception, which Oslo returns to the API node.  I'd imagine there is some way to have the Ali node extract the original exception or tell Oslo to return the only the original exception. <br><br>Tim<br><div class="gmail_quote"><div dir="ltr">On Thu, Sep 8, 2016 at 2:04 PM Aimee Ukasick <<a href="mailto:aimeeu.opensource@gmail.com">aimeeu.opensource@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">All --<br>

I stepped through the code with the pdb. I can't find anything wrong<br>
in the CongressException<br>
code.<br>
<br>
The traceback is being added by oslo_messaging/rpc/server.py  in<br>
_process_incoming<br>
This call that is throwing an exception: res =<br>
self.dispatcher.dispatch(message) but I haven't<br>
determined why.<br>

<br>
<br>
I can't figure out why oslo.messaging is throwing an exception, I<br>
assume I should go into the API and CLI cod and prevent the traceback<br>
from being displayed.<br>
<br>
Thoughts? Suggestions? Epiphanies?<br>
