I've been working though the Lightning trailhead modules. I know it used to work but the TWS app preview window now always fails with "Uncaught TypeError: Invalid value used as weak map key throws at https://....dev-ed.lightning.com/auraFW/javascript/-...../aura_proddebug.js:16252:26"
Not sure if it was installing R3 or something else I did to caues this but the preview always gives me this error now.
Is this known? Is there a logfile or something that I can look at to debug this a bit more?
Also: ctrl-c doens't work on the error window but (imo) it should.
