This action causes the {{WindowFn}} to be invoked to assign a window to the output value. But a merging {{WindowFn}} such as {{Sessions}} will be replaced by {{InvalidWindows}} at the GBK where merging is performed, so this is destined to crash. > It is almost certain that the window is not relevant, so we can quickly fix this by just windowing into the global window earlier and using vanilla {{output(...)}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
