POST API Request not Identical to running locally

[ks04]

Try this:

Code:

http = require('socket.http')
ltn12 = require('ltn12')

body = '{"iZoneV2Request": {"Type": 1,"No": 0,"No1": 0}}'
resp = {}

url = 'http://...'

res, code = http.request({
  url = url,
  method = 'POST',
  headers = {
    ['Content-Type']  = 'application/json',
    ['Content-Length'] = #body,
  },
  source = ltn12.source.string(body),
  sink = ltn12.sink.table(resp),
})

log(res, code, resp)

Sadly, same error

Code:

Event for 0/56/180 08.02.2023 11:24:21
* table:
[1]
  * string: {ERROR}
