Obscure stack trace and error `NoMethodError`

[illegalnumbers]

I am unsure what is causing this error but am willing to debug it. I ran rubocop autocorrect and fixed linting issues in my project and then was getting the following error consistently afterwards. Any ideas on what might be causing this? Every time I do a require 'byebug' and drop a debugger into a file I get this error.

     NoMethodError:
       undefined method `value' for nil:NilClass

If I run byebug rspec <myspec:line> it seems to work properly...

I ran into a similar error. Moving the require statements for byebug above all other requires seemed to resolve the problem for me.
