Docker build process fails at build chromium headless shell

[jonnym]

Build process log below:

Building on an Amazon EC2 Instance

Fails just as Ninja is trying to build out shell. Attempting to build headless-chromium to 81.0.4044.127

running 'vpython -vpython-spec src/.vpython -vpython-tool install' in '/build/chromium'
Warning: Running gclient on Python 3.
If you encounter any issues, please file a bug on crbug.com under the Infra>SDK component.
WARNING: Your metrics.cfg file was invalid or nonexistent. A new one will be created.
WARNING at build arg file (use "gn args <out_dir>" to edit):5:32: Build argument has no effect.
remove_webcore_debug_symbols = true
^---
The variable "remove_webcore_debug_symbols" was set as a build argument
but never appeared in a declare_args() block in any buildfile.

To view all possible args, run "gn args --list <out_dir>"

The build continued as if that argument was unspecified.

Done. Made 11649 targets from 2052 files in 12134ms
