Only assert\nwas added as a guard which checked if the size of generated camera config was\nequal to size of roles passed to it.\n\nIf the roles variable has an invalid/unsupported role, it will return\na nullptr and then trying to access a member on a nullptr for size comparison\nwill result in a segmentation fault.
