Re: Service workers

I used Seaside-REST in the past and it is great to "complement"
existing Seaside behavior or reusing some of the code, but if you were
to build a complete app from scratch maybe Teapot/Tealight
<https://github.com/astares/tealight> is a better fit for this case,
since you remove Seaside's server adaptor "middleware" from the stack.

I don't know whether Seaside's strongest feature (stateful server side
rendering) will be a big plus for PWAs, but I'm interested in your
experience nonetheless, since these kinds of approaches are
commonplace these days and might be useful for particular "sections"
of a full-fledged Seaside app.

As for your particular question you should put a breakpoint/halt at
the different entry points:
* ZnSeasideServerAdaptorDelegate>>handleRequest:
* WAServerAdaptor>>handleRequest:
* WARequestHandler>>handleFiltered:

Or to catch any error during the request:
WAServerAdaptor default server debugMode: true
