Examples (not sure which test each message comes from)

Error: Cannot resolve value for 'joint:transX_position' on prim '/joint_AD'; no authored value, no explicit default, and no solver mapping default.
Error: Cannot resolve value for 'joint:transX_velocity' on prim '/joint_AD'; no authored value, no explicit default, and no solver mapping default.

Error: Cannot resolve value for 'joint:nonexistent_attribute' on prim '/ant/joints/front_right_leg'; no authored value, no explicit default, and no solver mapping default.

From #602 (move up a verbosity level)

/builds/omniverse/newton-physics/newton/newton/_src/sim/graph_coloring.py:185: UserWarning: Color balancing terminated early: max/min ratio 2.000 exceeds target 1.100. The graph may not be further optimizable.

From #602 (Intentional CPU usage should not be printing this warning by default + move up a verbosity level)

/builds/omniverse/newton-physics/newton/newton/examples/cloth/example_cloth_hanging.py:147: UserWarning: Tiled solve requires model.device='cuda'. Tiled solve is disabled.
