uninitialized constant RspecApiDocumentation::Writers::JsonWriter (NameError)

[rlgreen91]

System info:

• Ruby 2.5.1
• Rails 5.2.0
• Rspec 3.7.0
• RspecApiDocumentation 5.1.0

I have my specs set up in spec/acceptance, as required. When I run bundle exec rake docs:generate, I get the following error:

/Users/rachel/.rvm/gems/ruby-2.5.1/gems/bootsnap-1.3.0/lib/bootsnap/load_path_cache/core_ext/active_support.rb:53:in `block in load_missing_constant': uninitialized constant RspecApiDocumentation::Writers::JsonWriter (NameError)

My configuration is set up as described in rails_helper.rb. This only occurs with trying to output as JSON - outputting as a different format, like HTML, works fine. I'm guessing it's not resolving the names correctly - it's looking for JsonWriter, not JSONWriter, as listed in the gem.

This is related to PR #359

Note: it also affects the :open_api format (since it's JSON based).

I am seeing this when cloning the repository and change

#example/spec/acceptance_helper.rb
..
config.format = [:open_api]
...

to config.format=[:json]

Experiencing this issue as well.

The same for me too !

I see the same issue too

I linked to the issue that probably created this above. If you are experiencing this check that out and see if it helps. My guess is there was some change between Ruby/Rails versions that flipped how this constant was interpreted and we will need to handle it with a check or alias the constant.

If someone experiencing this can put up a sample app with the problem and pinned to the versions they are experiencing it with via a .ruby-version and Gemfile.lock maybe we can narrow it down.

solution: change config.format = :json to config.format = :JSON.

[roramirez]

as @bf4 mention before this fix the issue for me.

Here is my Gemfile.lock

I merged #399, can everyone update to the git master branch and let me know if it solves your problems? If it does, I'll do a new release on rubygems.

[incubus]

It works, thanks!

[dikond]

I can confirm that it works on master.

[oestrich]

6.1.0 is out and has #399 in it.
