It was a problem with gem json version.
from ruby_193_docker.
Hi @jcserracampos I am glad you figured out your issue. I was going to say it appears that your code, or the json gem in this case, is using a Ruby 2.0 feature called double spat:

Often older gems don't list the Ruby version they are compatible with. For older applications I often have to manually limit the gem version in the gem file after doing some research and/or trial and error.
I'm also glad you found our Ruby 1.9.3 Docker image useful. If you have an suggestions for improving the image please let us know. All the best.

I had to fix some versions and it worked like a charm.
I am looking forward to submit PRs or open issues if I find something.
Thank you for your project!
