Start with the Robo test crash artifacts linked in the issue, then inspect RuntimeRouteStylingActivity and trace the obfuscated call path around the null reference. Reproduce the failure using the linked CircleCI or Firebase Test Lab run; done means the Robo test no longer produces this NullPointerException.
