Process never end in case of event sub-process triggered by a multi-instance sub-process

Flowable Engine
1

Hello,

Here the diagram of the sub-process that never ends.

It’s composed of a multi-instance subprocess and an event sub-process.
The multi-instance subprocess throw a HTTP404 BPMN error.
The event sub-process catch this error and do it’s job.

But the process never ends.
