Error Message not showing after custom authentication service node failure

We have set a default message for service node failures. However when the failure is due to a custom authentication service node time out, the default message is not successfully rendered. Also the task does not go back to the Dialog task after the node failure.

In the image, the service node reached timeout after 10 seconds, however the bot did not send an error message

The logs indicate an Intent Failed/Abandoned with reason service node failure. The bot did not go back to the Dialog Node that it was originally from

Hi @dionessa.biton,

We are able to replicate the issue and we have communicated this to our engineering team.
We will update you soon.
