JavaScript Error Reports - missing source, line and column number

Bug
10

I do not agree @deanmarktaylor. Looking at the logs on meta they are full of exactly this:

HTTP_HOST: meta.discourse.org
REQUEST_URI: /logs/report_js_error
REQUEST_METHOD: POST
HTTP_USER_AGENT: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36
HTTP_ACCEPT: */*
HTTP_REFERER: https://meta.discourse.org/t/nocaptcha-support/24107/1
HTTP_X_FORWARDED_FOR: 70.117.105.168, 10.0.0.202
HTTP_X_REAL_IP: 10.0.0.202

params:
  url: 
  line: 
  column: 
  window_location: https://meta.discourse.org/t/nocaptcha-support/24107/1

Hundreds of these, just like this. Zero backtrace, zero context, just a bunch of crying wolf with no information whatsoever.

And crying wolf is extremely harmful. It devalues any real substantive errors you might find in logs when they are cluttered with hundreds of useless noise entries, submitted by browser clients for who knows why.

I do not find it particularly illuminating to have a new “error” log entry every time a browser client HTTP ajax request fails… do you?
