before_session hook failed: NoMethodError: undefined method `chomp' for nil:NilClass

[ctrlaltdylan]

I'm using rails-pry to create a breakpoint with a binding.pry statement. This has worked just fine for just about ever. However now there's this fun new error message I'm not even sure how to being debugging the debugger:

before_session hook failed: NoMethodError: undefined method `chomp' for nil:NilClass
usr/local/bundle/gems/pry-0.12.2/lib/pry/pager.rb:116:in `block in write'
(see _pry_.hooks.errors to debug)

The result is the binding.pry statement is ignored and the code I intent to inspect continues to run.

I got a similar error message

before_session hook failed: NoMethodError: undefined method each' for nil:NilClass`

Still getting the same error and the execution never stops. Any lead on this?

Additional info: I'm using it with docker

Hey folks - sorry for necro'ing a 2 year old thing here, but the fix for this issue is to allow a psuedo-tty and to keep stdin open on Docker when running your containers. If you're running via docker-compose, make sure to add these lines to your Ruby/Rails service:

stdin_open: true
tty: true
