Issue importing JSON data into database - ruby-on-rails

Question

I've written a script that imports paginated JSON data from an api, encodes the data to UTF-8 and then writes it to a file.
I need to iterate over the data in the file to create records in my database, but am running to an error loading the file so I can do so.
The stack trace isn't telling me much about what's wrong; any help would be greatly appreciated!
code:
require 'net/http'
require 'uri'
require 'json'
require 'faker'
#imports APR User data from the zendesk api, iterates through it and populates the database with it.
uri = URI.parse("https://aprtechsupport.zendesk.com/api/v2/users.json")
request = Net::HTTP::Get.new(uri)
request.content_type = "application/json"
request.basic_auth("cbradford#blah.com", "blah32")
req_options = {
use_ssl: uri.scheme == "https",
}
#response = Net::HTTP.start(uri.hostname, uri.port, req_options) do |http|
http.request(request)
end
res = #response.body
res.force_encoding("utf-8")
resEncoded = JSON.parse(res)
users = resEncoded
#data = {}
#data.merge(users)
results = []
results << resEncoded
puts results
while users["next_page"]
newUri = users["next_page"]
uriLoop = URI.parse(newUri)
puts newUri
requestLoop = Net::HTTP::Get.new(uriLoop)
requestLoop.content_type = "application/json"
requestLoop.basic_auth("cbradford#blah.com", "blah32")
req_optionsLoop = {
use_ssl: uriLoop.scheme == "https",
}
#responseLoop = Net::HTTP.start(uriLoop.hostname, uriLoop.port, req_optionsLoop) do |http|
http.request(requestLoop)
end
dataEncoded = #responseLoop.body
dataEncoded.force_encoding("utf-8")
resLoop = JSON.parse(dataEncoded)
results << resLoop
updateUri = resLoop["next_page"]
users["next_page"] = updateUri
end
puts "hash created Successfully!"
puts results
File.write('blahzendeskusers1.json', results)
puts "File Created Successfully!"
file = File.read('blahzendeskusers1.json')
usersLoop = JSON.load(file)["users"]
usersLoop.each do |a|
User.find_or_create_by(:zendesk_id_int => a["id"], :url => a["url"], :name => a["name"], :email => a["email"],
:phone => a["phone"], :role => a["role"], :default_group_id => a["default_group_id"], :external_id => a["external_id"],
:tags => a["tags"]
)
end
