Malformed params creation on POST when params added to body about rswag

[pbelouin-mpiwg]

Damn! I needed to set the "consume" value to 'application/json'! I'll close the issue but leave that here just in case somebody googles it, if that's ok.

I've a similar issue but consumes is set to application/vnd.api+json (I tried application/json too). The result is quite similar to yours:

<ActionController::Parameters {"{\"data\":{\"type\":\"bank_accounts\",\"attributes\":{\"bank_id\":\"some_uuid\",\"login\":\"my_login\",\"password\":\"my_password\"}}}"=>nil, "format"=>:json, "controller"=>"bank_accounts", "action"=>"link"} permitted: false>

Here is my code. What am I missing?

path '/bank_accounts/link' do
  
    get 'Create a link between a bank and the Bank API' do
      consumes 'application/vnd.api+json'
      produces 'application/vnd.api+json'
      
      parameter name: :params,
                in: :body,
                description: 'data of the futur bank account',
                required: true,
                schema: {
                  type: :object,
                  properties: {
                    data: {
                      type: :object,
                      properties: {
                        attributes: {
                          type: :object,
                          properties: {
                            bank_id: {
                              type: :string,
                              format: 'uuid',
                              description: 'ID of a bank',
                              example: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'
                            },
                            login: {
                              type: :string,
                              description: 'Login of the user to connect to the selected bank'
                            },
                            password: {
                              type: :string,
                              description: 'Password of the user to connect to the selected bank'
                            }
                          }
                        },
                        type: {
                          type: 'string',
                          description: 'bank_accounts'
                        }
                      }
                    }
                  }
                }
    
      describe 'with valid parameters' do
        response '200', 'Create a bank account linked to the bank' do
          let(:params){ { data: {type: 'bank_accounts', attributes: {bank_id: 'some-uuid',
                                                                  login: 'my_login',
                                                                   password: 'my_password'} }}}

          schema '$ref' => '#/definitions/BankAccount'
        
          run_test!
        end
end

Edit: I've switched from get to post and it's working like a charm. Thanks for your issue. It helped a lot!
