Displaying extensions returns "Undefined index:data" error in php-asmanager.php

When I choose to display my extensions, FreePBX 13 returns a stack of errors in red boxes on the right hand side that include “Undefined index: data”.

In the JSON panel on the right hand side of my Firefox 45.6.0 Web Console the error is displayed as:

error: Object
type: "Whoops\Exception\ErrorException"
message: "Undefined index: data"
file: "/var/www/html/admin/libraries/php-asmanager.php"
line: 1525

Why can’t I display my extensions?

FreePBX runs in a privileged LXC container. Both host and container run Gentoo.

asterisk -V
Asterisk 13.13.1

Roughly followed the Ubuntu guildeline.

The asterisk manager connection is corrupt or faulty. Beyond that not much we can tell you.

I get stacks of:

== Manager ‘admin’ logged off from
== Manager ‘admin’ logged on from

in my asterisk console when using Freepbx.

How do I formally test my asterisk manager connection?

This doesn’t have anything to do with the original question.

What are you trying to do (in your own thread, please).

I am attempting to display the extensions of my FreePBX 13 installation without getting those Undefined index: data errors.
