# Transport

The HTTP and socket seams. What a client can do to them, and what a shutdown
can do to us.

## mavweb errors cannot be traced [#689] {#errors}

Costs: some handlers return the raw internal error, which discloses internals.
Others return a generic one with no identifier, which cannot be joined to its
log line. There is no request-id middleware to join them.
Revisit when: a reported UI failure cannot be found in the log.
Workaround: read the log by timestamp.
