Smartthings status update

[Ozturker]

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
