Smartthings status update

[CristianAgata]

I receıved below 422

Code:

* string: Request body: {"commands":[{"capability":"switch","command":"on","component":"main"}]}

* string: SmartThings response code: 422

* string: SmartThings response body: {"requestId":"391879646930462279","error":{"code":"ConstraintViolationError","message":"The request is malformed.","details":[{"code":"BodyMalformedError","target":"httpRequestBody","message":"The request body is malformed and cannot be processed by server.","details":[]}]}}

Here is the full code

Code:

local https = require('ssl.https')
local json  = require('json')
local ltn12 = require('ltn12')



-- ️ put your smartthings pat here
local token = '*************'

local livingr_cam_id = '**************************'


-- Camera KNX group objects (choose addresses as needed)
local ga_cam_onoff_set     = grp.create({ datatype = dt.bool,    address = '33/4/1', name = 'Camera On/Off' })
local ga_cam_onoff         = grp.create({ datatype = dt.bool,    address = '33/4/2', name = 'Camera On/Off Status' })
local ga_cam_motion        = grp.create({ datatype = dt.bool,    address = '33/4/11', name = 'Camera Motion Detected' })
local ga_cam_sound         = grp.create({ datatype = dt.bool,    address = '33/4/12', name = 'Camera Sound Detected' })


local cam_set = grp.getvalue(ga_cam_onoff_set)  -- Set
local cam_set_status = grp.getvalue(ga_cam_onoff)  -- Status



-- Helper to turn camera on or off using a raw JSON string
local function set_camera_onoff(cam_id, state)
  local cmd = state and 'on' or 'off'
 
local body = require('json').encode({
  commands = {
    {
      component = 'main',
      capability = 'switch',
      command = cmd,
    }
  }
})


  log('Request body: ' .. body)

  local sink_tbl = {}
  local res, code = https.request({
    url     = 'https://api.smartthings.com/v1/devices/' .. cam_id .. '/commands',
    method  = 'POST',
    headers = {
      ['authorization'] = 'Bearer ' .. token,
      ['content-type']  = 'application/json; charset=utf-8',
      ['accept']        = 'application/json',
    },
    source = ltn12.source.string(body),
    sink   = ltn12.sink.table(sink_tbl),
  })


  local response_body = table.concat(sink_tbl)
  log('SmartThings response code: ' .. tostring(code))
  log('SmartThings response body: ' .. response_body)
  return res, code, response_body
end



if cam_set == true then
    if cam_set_status == false then
        set_camera_onoff(livingr_cam_id, true)
  end
elseif cam_set == false then
    if cam_set_status == true then
        set_camera_onoff(livingr_cam_id, false)
    end
end
     

Here is the working postman cURL

Code:

curl --location 'https://api.smartthings.com/v1/devices/***************************/commands' \
--header 'Content-Type: application/json' \
--header 'Authorization: **********' \
--data '{
    
              "commands": [
                {
                  "component": "main",
                  "capability": "switch",
                  "command": "on"
} ]
}'

Thank you for the support

Hi, try to add this in the header, for me works
['content-length'] = #body,
Best regards Cristian
