'Could not copy files' error is silent

See title. Something in my build config is likely misconfigured, but I'm having a heck of a time trying to figure out what it is because the error from cpr is snuffed out, which is hardly helpful.

[EDIT] Doing some manual debugging and the silent failure may be occurring in cpr itself. Not sure yet, but if so, then we can probably disregard my message above. :P

Welp, classic PEBKAC, most likely. The 'silent error' I was getting was caused by a typo in destPath that managed to resolve to a valid path on my local drive rather than the network share I was trying to copy to. Works now. 🌵

The presence of ember-cli's SilentError kinda threw me for a loop, though, and I'm having issues trying to trick cpr into throwing an error (as it prefers to run out of memory rather than error out in vase of an invalid path o_O). It's possible that maybe this works as expected? I can't figure out how to truly check, heh.

If nothing else helps we can of course check the validity of the destPath before invoking cpr
