Regexp doesn't work

[jazzl0ver]

Hi and thanks for the awesome app!

I'm trying to use my own haproxy log format. The log entry has some captured request headers which are enclosed with braces:

... {||573|Delivery%20Map/11 CFNetwork/758.5.3 Darwin/15.6.0} ...

To catch that part I use the following regexp (check captured_request_headers line):

    def self.compose_regexp(millisecs, backends, counters, connections, queues)
      %r{
        (#{ip_address}):\d+\s # client_ip ':' client_port
        \[(#{timestamp('%d/%b/%Y:%H:%M:%S')})#{millisecs}\]\s # '[' accept_date ']'
        (\S+)\s # frontend_name
        #{backends}
        #{counters}
        (\w|-)(\w|-)(\w|-)(\w|-)\s # termination_state
        #{connections}
        #{queues}
        "([^"]*)"\s # '"' http_request '"'
        (\d+)\s # status_code
        (\S+)\s # captured_request_cookie
        ({[\w\W]*})\s # captured_request_headers
        (\S+)\s # captured_response_cookie
        (\S*)\s? # captured_response_headers
        ireq_size\=(\d+)\s # bytes_sent
        resp_size\=(\d+)\s # bytes_read
      }x
    end

Online regexp checker successfully works for that part: https://regex101.com/r/fM4mW5/1

But your app throws an exception:

If I remove that regexp and the appropriate log part, everything works like a charm. There's also no exception if I remove * (the star) from "({[\w\W]*})".

Can you please help me with that?

This regexp doesn't work as well:

({[.\w| %/]*})\s
