This should fix it #868

Edit: see comments below

[braydonf]

The nodejs version isn't mentioned in this issue, however it's likely a duplicate of #754.

[braydonf]

Also related, such errors are not visible unless the process is run in the foreground, see #747 which can make visibility of errors difficulty to debug.
