Opening a google doc file from command line ...

[Joe Lowder]

When I use the following string (1) to open a google doc
file from the command line, it works fine, but gives
the ERROR message quoted (2) second below:

(1) google-chrome --app --new-window
https://docs.google.com/document/d/1CtuZyh-vXIvOk4J8sCLFpKTKHUtw4j5m_UqaPMpIdbM/edit

(2)
[16506:16506:0426/192107.652606:ERROR:browser_dm_token_storage_linux.cc(100)]
Error: /etc/machine-id contains 0 characters (32 were expected).
Fontconfig warning: "/etc/fonts/fonts.conf", line 86: unknown element
"blank"
Opening in existing browser session.

Can anyone tell me why and how to stop or remedy this error?
