1546216 - Errors raised when running mach try chooser

Status: RESOLVED DUPLICATE of bug 1520573

(Developer Infrastructure :: Try, defect)

Description

[(No longer employed by Mozilla) Aaron Klotz]

I'm running MozillaBuild on Windows 10, if that matters.

Everything still seems to work, however once the web page is loaded, my terminal outputs a bunch of spew:

$ ./mach try chooser
Task configuration changed, generating target task set
Starting trychooser on http://127.0.0.1:5000
 * Serving Flask app "tryselect.selectors.chooser.app" (lazy loading)

This didn't occur previously; it started after I updated central.

Interesting, this one is slightly different than the more common Broken Pipe error. But the solution for both is the same (just hide them), so going to dupe.
