<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: small;">
<div>I'm building my first non-trivial Erlang application. I've gotten it working in the shell. Now I'm trying to build a release using rebar. "rebar generate" succeeds, but when I try to run the application I get the error below. I'm trying to follow these
tutorials:</div>

<div>I have named both my application and my node "session". The error seems rather unhelpful, so any suggestions on how to debug are appreciated.</div>

<div>thanks,</div>
