no implicit conversion of nil into String

I had an error running on our local build and it would give the error when running the rails console

After a lot of investigating, it was an error in our code. The line of code seems to bear no relevance to the error.

code

redo if @counter <= 5

which actually causes the error

(eval):2: Can't escape from eval with redo

This took some significant time to debug as the error message was seemingly unrelated to the bad code.
Is there a reason why the error message wasn't explicit about the issue and it's location?
