Hello,
this behaviour is there from the beginning, maybe it went unnoticed so
far and if not in the documentation, it can be updated to reflect it.
While I was not the developer of the config interpreter at that time,
the reason behind is that the processing of the reply is considered failed.
Because of it, the default config file has return as last action in
these routing blocks.
Cheers,
Daniel

Hi James,
sure, you can open a github issue about it. If it’s a bug it should be fixed, if its not
a bug at least some documentation would be great.
Cheers,
Henning

Thanks, Henning
Yes, I added a return statement and it works around the problem in this case,
but I'd not like to find the bug appearing somewhere else (in another route for
example).
Should I open a Github Issue for this sort of thing?

Hello James,
good point, we were able to confirm this. There is an easy work-around by
just adding an if statement around it.
Nevertheless, I agree that this is unexpected
behaviour and should be
further investigated.
Cheers,
Henning
