Hm.. at first glance it seems odd to put the special logic in the http response handler instead of just having the internal state reflect that the task is terminal (after all.. it is terminated). Cant't the agnet move the tasks to an appropriate terminal state prior to "completing" the executor? That way, we also will know that the endpoints are accurately reflecting the in-memory state. - Benjamin Mahler On May 1, 2019, 2:13 a.m., Joseph Wu wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
