Capistrano not creating puma pid when deploying to production - ruby-on-rails

Question

I have a simple rails app that I am trying to deploy to a production server using Capistrano, but it appears to fail when trying to create the puma.pid.
When I check the the puma.access.log I see the following,
/home/capin/.rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/uri/rfc3986_parser.rb:66:in `split': bad URI(is not URI?): unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock (URI::InvalidURIError)

from /home/capin/apps/Tshirt/shared/bundle/ruby/2.2.0/bin/puma:23:in `<main>'
Does anybody know why puma would display this error? I can post more configuration files if need be too.

# role-based syntax
# ==================
# Defines a role with one or multiple servers. The primary server in each
# group is considered to be the first unless any hosts have the primary
# property set. Specify the username and a domain or IP for the server.
# Don't use `:all`, it's a meta role.
# role :app, %w{deploy#example.com}, my_property: :my_value
# role :web, %w{user1#primary.com user2#additional.com}, other_property: :other_value
# role :db, %w{deploy#example.com}
# Configuration
# =============
# You can set any configuration variable like in config/deploy.rb
# These variables are then only loaded and set in this stage.
# For available Capistrano configuration variables see the documentation page.
# http://capistranorb.com/documentation/getting-started/configuration/
# Feel free to add new variables to customise your setup.
# Custom SSH Options
# ==================
# You may pass any option but keep in mind that net/ssh understands a
# limited set of options, consult the Net::SSH documentation.
# http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start
#
# Global options
# --------------
set :ssh_options, {
keys: %w(/Users/capin/.ssh/id_rsa),
forward_agent: true,
auth_methods: %w(publickey password)
# port: 4321,
}
# set :ssh_options, {
# keys: %w(/home/rlisowski/.ssh/id_rsa),
# forward_agent: false,
# auth_methods: %w(password)
# }
#
# The server-based syntax can be used to override options:
# ------------------------------------
# server 'example.com',
# user: 'user_name',
# roles: %w{web app},
# ssh_options: {
# user: 'user_name', # overrides user setting above
# keys: %w(/home/user_name/.ssh/id_rsa),
# forward_agent: false,
# auth_methods: %w(publickey password)
# # password: 'please use keys'

Looks like mistake in your puma/capistrano configuration file. I think you put the line unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock into single quotas instead of double and string interpolation is not working :)
UPDATE:
check your puma_bind value, should be
set :puma_bind, "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock"
in double quotas
