Flexirest to handle string array - ruby-on-rails

Question

I'm using Flexirest to make a request to an endpoint that returns an array of strings with Content-Type: application\json.
This is the model:
class Neighborhood < BaseModel
get :by_location, "/neighborhoods/by_location"
end
And this is how I make the request:
def get_neighborhood_list
city_to_use = ApplicationHelper.user_location[:city] || Rails.configuration.default_location[:city]
#hoods = Neighborhood.by_location(city: city_to_use)
end
And this is called but it only reaches the super line since it breaks inside there:
def handle_response(response, cached = nil)
result = super(response, cached)
setup_paging_variables result, response
setup_paging_variables result.data, response if result.respond_to? 'data'
result
end
The endpoint returns an array of strings:
[
"Ahwatukee Foothills Village",
"Alhambra",
"Camelback East Village",
"Central City",
]
With this headers
My problem is that Flexirest is treating the strings as json objects instead due to the value on the Content-Type header.
I get this error
TypeError: no implicit conversion of Symbol into Integer
on this line on the if attributes[:_links].
It's getting there because hal_response? is true
Do I need to do something in particular in order for Flexirest to stop behaving like this?
Update
I guess I didn't explained it properly. The error is occurring on the gem side.
Here is the full error:
TypeError - no implicit conversion of Symbol into Integer:

app/controllers/application_controller.rb:93:in `get_neighborhood_list
The if attributes[:_links] line is part of the gem code, and it's here on this line
When it reaches this line the value of attributes is one of the strings inside the response, for instance: attributes = "Ahwatukee Foothills Village". That's why it gives the error.
What I'm trying to figure out if there is a way (maybe something in the configuration) that I can use Flexirest to handle this kind of responses.

This is a old question but thought I'd answer it. you need to add
plain: true
in your model like below.
class Neighborhood < BaseModel
get :by_location, "/neighborhoods/by_location", plain: true
end
It will then return the string array
