devtool profiling fails with Uncaught Error

[radiovisual]

Description

When following the profiling instructions in maintaining.md:

$ devtool node_modules/ava/profile.js test.js

I get an Uncaught Error (see below). If it helps, I ran the profiler against the AVA tests in https://github.com/sindresorhus/generator-nm

Error Message & Stack Trace

Here is the text from the screenshot above:

(This issue is related to the archived issue #798)

Like #988, @avajs/core any ideas?

Is this something we should still include? Seems prone to breaking…

[sindresorhus]

@novemberborn It can be useful, especially until we do #929. No idea why it's currently breaking though.

Possibly related to this? Experience-Monks/devtool#74

[novemberborn]

Could anybody confirm whether this is still an issue?
