undefined method in split function of rails 3

[coderhs]

My version of rails is 3.2.13

When i run rake js:routes, i get the following error:

rake aborted!
undefined method `split' for #<Journey::Path::Pattern:0x000000077b8a20>
/home/hsps/crm-sages/lib/tasks/js.rake:63:in `block in generate_routes_for_rails_3'
/home/hsps/crm-sages/lib/tasks/js.rake:61:in `generate_routes_for_rails_3'
/home/hsps/crm-sages/lib/tasks/js.rake:8:in `block (2 levels) in <top (required)>'
Tasks: TOP => js:routes
(See full trace by running task with --trace)

I fixed this issue by changing

route.path.split("(")[0]

to

route.path.spec.to_s.split("(")[0]}
