Usually happens between deploys. I wouldn't mind making this small change:

diff --git a/lib/rollbar/item.rb b/lib/rollbar/item.rb

       nil

but it might shadow a bigger issue with it.

Thanks in advance.

Hey @jlhonora, thank you very much for opening this issue. I think I've found the reason of this crash. I'll fix this and release a new gem version in few hours ok?

Thanks again.

Awesome, thanks for the fast response.
