Quick Start

  • Install globally using npm install -g akamai-error-lookup
  • Configure your Akamai API credentials in auth.edgerc
  • Run hashref [errorReference]

Output Example


A command line utility to lookup Akamai error reference numbers (e.g. Reference #18.2d351ab8.1557333295.a4e16ab).

If you work on a website hosted behind Akamai's CDN you will, on occasion, see an Akamai Reference # error number. These occur when Akamai catches an error, as opposed to the origin serving an error, such as a DNS resolution failure or an origin connection error.

In these scenarios Akamai reports an error reference number:

error - Service Unavailable - DNS failure

Using hashref you can lookup the details of the #Ref error number to diagnose the root cause of the error:

hashref 11.2e373217.1558103133.1dedf6b

usage example


npm install -g akamai-error-lookup


You'll need to create an auth.edgerc file and configure it with your Akamai API credentials as described here.

You can save auth.edgerc in either the current directory or in the home directory (node -p require('os').homedir()).

Using the home directory means you can install the package globally and call hashref from any location.

If the auth.edgerc file is not found you'll receive the following error message:

auth file not found


hashref [errorReference] [options]


--decode <true|false>            Enable or disable decoding of URLs and user-agent [true]
--no-color                       Switches off colour output
--version                        Display version number
--help                           Display this help


By default all output will be decoded, so that fields such as user-agent and URL are more readable. Use --decode false to switch this off.


If your terminal has problems rendering the colour output then you can switch it off by using --no-color.


Prints out akamai-error-lookup's version number.


Displays the help screen.

Verbose output

The default terminal output contains a selective subset of the more salient fields returned by Akamai's API.

The full json response is automatically written to the operating system's default directory for temporary files (node -p require('os').tmpdir()). The location is displayed as part of the terminal output:

Writing full response to [C:\Users\foo\AppData\Local\Temp\11.2e373217.1558514903.f6c71e.json]

Note: On Linux systems this will be /tmp rather than /var/tmp which means these files will not persist a system reboot. If you want to retain them, copy them elsewhere.


akamai-error-lookup uses the npm package debug. If you set the environment variable debug to hashref you'll see full debug output.


set debug=hashref
hashref [errorReference]


DEBUG=hashref hashref [errorReference]


node akamai-error-lookup [errorReference]
