>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: scheduler
>    Affects Versions: 1.7.0

> The issue is pretty simple. It looks like if you have a DAG with a {{schedule_interval=None}}, you can't use an SLA with it. I'm running Airflow 1.7.0 and it runs into trouble in jobs.py at this line around line 255.
>                 {{dttm = dag.following_schedule(dttm)}}
> I assume because there is no schedule to follow.
> I've provided a simple example to illustrate the issue. It's a task that will take 2 minutes but the SLA is set at 1 minute. The SLA is not enforced.
