I am moving my rails application to rails only api but jbuilder is returning a blank screen

[hassanrbh]

I check all of the previous talks about the same problem , I suppose to solve it with include ActionView::Rendering but when I include it, I get a different error saying undefined method 'include?"

/Users/mac/.rvm/gems/ruby-2.7.0/gems/actionpack-6.1.4.1/lib/abstract_controller/helpers.rb:148:in block in helper': undefined method include?' for nil:NilClass (NoMethodError)

include ActionController::Cookies

[hassanrbh]

there is no one to response ?

[hahmed]

@hassanrbh could you provide more information about the issue you are facing? Ideally a repo that shows the problem... there is not enough to go by to comment on what's going wrong

[p8]

Looking at the source of the error it seems _helpers is nil.
https://github.com/rails/rails/blob/6-1-stable/actionpack/lib/abstract_controller/helpers.rb#L148
Could you post the whole backtrace of the error?

@p8 yeah sure dude, one minute

[hassanrbh]
