rails json response not able to build - ruby-on-rails

Question

I have a method in controller creat
it respond generate array of records like
[{"code"=>500, "body"=>{"message"=>"Ivalid data or you enter a duplicate data"}}, {"code"=>200, "body"=>{"id"=>"775606be-d3ae-4b43-a820-74022f8f273f"}}, {"code"=>500, "body"=>{"message"=>["Name has already been taken"]}}, {"code"=>500, "body"=>{"message"=>[:Error, ["No Fable", "level not found in rand", "Invalid or Blank e"]]}}]
now I want to make it n a json response
def create
k=[{"code"=>500, "body"=>{"message"=>"Ivalid data or you enter a duplicate data"}}, {"code"=>200, "body"=>{"id"=>"775606be-d3ae-4b43-a820-74022f8f273f"}}, {"code"=>500, "body"=>{"message"=>["Name has already been taken"]}}, {"code"=>500, "body"=>{"message"=>[:Error, ["No Federation ID in Cookie ID\n# Mapping Table", "level not found in Brand", "Invalid or Blank Source Type"]]}}]
# render create.json.jbuilder
render json: k, status: 200
end
so it generate
{
"bulks": [
{
"code": 500,
"body": {
"message": "Ivalid data or you enter a duplicate data"
}
},
{
"code": 200,
"body": {
"id": "7754322222222f"
}
},
{
"code": 500,
"body": {
"message": [
"Name has already been taken"
]
}
},
{
"code": 500,
"body": {
"message": [
"Error",
[
"No Fable",
"level not found in Brand",
"Invalid or Blank Source Type"
]
]
}
}
]
}
it added bulks: while render the json in controller
how can I remove the bulks the expected json would be
{ {
"code": 500,
"body": {
"message": "Ivalid data or you enter a duplicate data"
}
},
{
"code": 200,
"body": {
"id": "775606be-d3ae-4b43-a820-74022f8f273f"
}
},
{
"code": 500,
"body": {
"message": [
"Name has already been taken"
]
}
},
{
"code": 500,
"body": {
"message": [
"Error",
[
"No Fable",
"level not found in Brand",
"Invalid or Blank Source Type"
]
]
}
} }
Please help
