strange backslash when json.write

[Hadeel]

Hi !

I am working on LM app development and below is the index.lp code.
From the commandline I can use the endpoint like this , with a request body. It returns the result like this : {"results":[{"alias":"6\/6\/1","value":true}]}
Is there a way to remove the backslash in from the result json string ? 

Thank you !

{
    "commands":[
        {
            "alias":"6/6/1",
            "value":true
        }
    ]
}

Code:

<?
  require('json')
  require('apps')
  params = ngx.req.get_body_data()
  params = json.pdecode(params)

  require('custom.utils')

  results = {}
  if params ~= nil then
    for index, command in ipairs(params.commands) do
      if type(command.alias) ~= nil or type(command.value) ~= nil then
        res = grp.write(command.alias, command.value) or false
        table.insert(results, {value = res, alias = command.alias})
      end
    end
    results = {
      results = results
    }
    write(json.encode(results))
  end
