Http request - FatMax - 15.12.2024

I am struggling a litte bit with understanding what is going wrong here:

Code:
function set_light_state(id, is_on)
    local url = base_url .. 'devices/' .. id
    local payload = json.encode({
        {
            attributes = {
                isOn = is_on
            }
        }
    })

    response_body = {}
    local _, code = https.request{
        url = url,
        method = "PATCH",
        headers = {
            ["Authorization"] = "Bearer " .. access_token,
            ["Content-Type"] = "application/json"
        },
        source = ltn12.source.string(payload),
        sink = ltn12.sink.table(response_body),
        verify = false
    }

    -- Check respnse
    if code == 200 then
        log('Light was set to ' .. (is_on and 'på' or 'av'))
    else
        log('Error updating light state. Status code: ' .. tostring(code))
        log('Server response: ' .. table.concat(response_body))
    end
end


The server throws an error when using this function. The response is not helpful as it seems like an internal server error.

I am guessing it has something to do with the payload, as the curl opposite of this function works fine:

Code:
curl -X PATCH "https://{IP}}/v1/devices/{ID}" \
              -H "Authorization: Bearer BEARER_TOKEN" \
              -H "Content-Type: application/json" \
              -d '[{"attributes":{"isOn":true}}]' \

Is the payload formatted correctly as in the curl?

You are missing Content-Length header:
Code:
["Content-Length"] = #payload,

That did the trick, thank you!
