Hi,
I built a simple Web AppBuilder application in ArcGIS Online (with all data coming from hosted feature services), but I'm getting strange behavior from Esri's default print service. When trying to use any other layout than MAP_ONLY, it either foes nothing and instantly returns only an "Error, try again" warning as shown below. When I hover over the error, a tooltip says "Cannot read property renderer of undefined". Oddly, MAP_ONLY works fine. Also odd is that I checked several other apps I've previously built, and the print service works fine on those.
I've tried rebuilding the app from scratch to no avail, and tried a different browser. Any insight or workaround is appreciated. Below is a screenshot of the app as well as the developer console in Chrome.
