<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>Creating an enqueue task with an end event falsely throws an error during runtime:</p>
<p>Non existent successor (Event_077nxdr) from ECA.... (cpb_01_01) for event eca_queue.processing_task.</p>
<pre> id: eca_enqueue_task_1hs3fvc<br> condition: ''<br> eca_enqueue_task_1hs3fvc:<br> label: 'Enqueue a task'<br> plugin: eca_enqueue_task<br> configuration:<br> task_name: xyznext<br> task_value: ''<br> tokens: cccnid<br> successors:<br> -<br> id: Event_077nxdr<br> condition: ''</pre><p>Turns out it always happens for the end event.</p>
