Hello
I have smashing install of raspberry pi 3b+ with the newest raspbian-stretch. when I enter the following in bash:
curl -d '{ "auth_token": "YOUR_AUTH_TOKEN", "text": "Hey, Look what I can do!" }' \http://localhost:3030/widgets/welcome
the following error occurs:

What is my problem ???
Can't really help. It worked for me with smashing vanilla install on Ubuntu LTS.
Even tried to use same sinatra version as you (both sinatra and sinatra-contrib). But it still worked. Ruby 2.5 on Ubuntu LTS.

Installed on OS X 10.13.6
@qpac I managed to fix it!
The version of Ruby bundled with OS X is seemingly incompatible, so I updated to the latest version, restarted my machine, restarted the dashboard, then I could curl and update the dashboard.
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install rbenv ruby-build
# Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile
# Install Ruby
rbenv install 2.6.1
rbenv global 2.6.1
ruby -v
Then restart, launch your dashboard, and you should be good to go!
@qpac see @MiskonceptioN 's comment. I couldn't reproduce it on Ubuntu LTS' Ruby and smashing. Feel free to re-open if that doesn't work for you. And thanks for reporting the fix for the issue @MiskonceptioN !
