TypeError (no implicit conversion of Array into String) active record on create method rails

Question

I have the following model

class Business < ApplicationRecord {
               :id => :integer,
    :business_name => :string,
         :place_id => :string,
          :surburb => :string,
             :type => :text,
       :created_at => :datetime,
       :updated_at => :datetime
}

I am sending a JSON object to my api create method this is my object

business_params = {
    :business_name => "Endah Parade",
          :surburb => "Taman Sri Endah",
             :type => [
        [0] "premise",
        [1] "point_of_interest",
        [2] "establishment"
    ],
         :place_id => "ChIJixfh-49KzDERePyk34svbaY"
}

In my controller i run the following

business = Business.create!(business_params)

but i get the error TypeError (no implicit conversion of Array into String). My type column was defined as this

change_column :businesses, :type, :text, array: true, default: [], using: "(string_to_array(type, ','))"

So at least i know that my type column can accept array but i am not sure why i get this error.

In my Business Model, i added the following as well serialize :type, Array but it also doesnt help. I get the same error.

How can i solve this issue?

I am using Rails 5.1

That's because Rails uses type column by default for STI implementation.

Disabling of STI should help:

class Business
  self.inheritance_column = nil
end
