undefined method `symbolize_keys' for Warden::JWTAuth:Module (NoMethodError)

[r6m]

Please, for a bug report fill in the following template. Before that, make sure to read the whole README and check if your issue is not related with CORS.

Feature requests and questions about devise-jwt are also accepted. It isn't the place for generic questions about using devise with an API. For that, read our wiki page or ask somewhere else like stackoverflow

Expected behavior

Actual behavior

/Users/reza/.rbenv/versions/2.6.5/lib/ruby/gems/2.6.0/gems/warden-jwt_auth-0.3.6/lib/warden/jwt_auth.rb:38:in `block in <module:JWTAuth>': undefined method `symbolize_keys' for Warden::JWTAuth:Module (NoMethodError)

Steps to Reproduce the Problem

1. add gem 'devise' and gem 'devise-jwt', '~> 0.5.9' to Gemfile, then run bundle
2. do any generate like bundle exec rake secret

Debugging information

Provide following information. Please, format pasted output as code. Feel free to remove the secret key value.

• Version of ruby: 2.6.5
• Version of devise-jwt in use: '~> 0.5.9'
• Version of rails in use: 6.0.2.1
• Output of Devise::JWT.config
• Output of Warden::JWTAuth.config
• Output of Devise.mappings
• If your issue is related with not getting a JWT from the server:
  • Involved request path, method and request headers
  • Response headers for that request
• If your issue is related with not being able to revoke a JWT:
  • Involved request path, method and request headers

Saw this after posting it myself, I have provided more details here. If anyone could help.

[waiting-for-dev]

For now lock you dry-configurable version to 0.9. I'll take a look as soon as possible.

[waiting-for-dev]

Fixed. It was a regression in dry-configurable and it has been fixed there. I've released v0.4.1 of warden-jwt_auth (which is the core engine for devise-jwt) depending on a version at least equal that the one containing the fix. So, in order to fix it for devise-jwt users, you just need to update warden-jwt:

bundle update --source warden-jwt_auth

[waiting-for-dev]

Hold on, there're still some issues to be resolved. So keep with the version of dry-configurable locked. I'll report on news.

Still seeing the following error when I don't freeze dry-configurable

[Ryuday]

Well I'm new to ruby ​​on rails, however in my case you can fix that error by replacing the file
gems > warden-jwt_auth-0.4.1 > lib > warden > jwt_auth.rb

value by [['POST', %r{^/login$}]] in:

52  setting(:dispatch_requests, []) do |value|
53    upcase_first_items(value)
54  end

and value by [['DELETE', %r{^/logout$}]] in:

63  setting :revocation_requests, [] do |value|
64    upcase_first_items(value)
65  end

However, I don't know what consequences it has on the proper functioning of the gem.

The error comes from this method in the file
gems > dry-configurable-0.11.4 > lib > dry > configurable > setting.rb

115  def evaluate
116    @value = constructor[input.equal?(Undefined) ? nil : input]
117  end

when the input variable equals undefined, it loads the null value giving the following error

jwt_auth.rb:92:in `upcase_first_items': undefined method `map' for nil:NilClass (NoMethodError)

[waiting-for-dev]

As it's taking longer than expected to be fixed upstream in dry-configurable, I have released a new version of warden-jwt_auth 0.4.2 which locks itself dry-configurable version. This way, once it's updated there I'll just release a new version and it'll be transparent for the user.

So, to fix it when using devise-jwt, just run bundle update --source warden-jwt_auth
