This part of the instructions were missed:
https://wiki.squid-cache.org/Features/AddonHelpers#helper-protocols
"
For every line sent by Squid exactly one line is expected back. Some 
script language such as perl and python need to be careful about the 
number of newlines in their output.
"

If your helper received something like this (with concurrency channel-id 
"1"):

  "1 bob 192.0.2.1"

It should produce a line like:
   "1 OK proxy=all"

If no concurrency channel-id is received, then output is the same but 
without sending channel-id back and MUST be sent in same order as received.

I do recommend using concurrency. It can help further debug issues with 
helpers responding incorrectly.
