Main process Failed:

Error-->/opt/dtgbot/dtg_domoticz.lua:111: attempt to get length of local 'result' (a nil value)stack traceback: /opt/dtgbot/dtgbot.lua:24: in function '__len' /opt/dtgbot/dtg_domoticz.lua:111: in function 'Domo_Variable_List_Names_IDXs' /opt/dtgbot/dtg_main_functions.lua:15: in function 'DtgBot_Initialise' /opt/dtgbot/dtgbot.lua:119: in function </opt/dtgbot/dtgbot.lua:113> [C]: in function 'xpcall' /opt/dtgbot/dtgbot.lua:112: in main chunk [C]: in ?

this happens because:

function Domo_Variable_List_Names_IDXs() local record, decoded_response, result decoded_response = Domo_Variable_List() result = decoded_response["result"] <--------------it is nil here local variables = {} for i = 1, #result do record = result[i] if type(record) == "table" then variables[record["Name"]] = record["idx"] end end return variables end

proposed fix is

-- returns idx of a user variable from name function Domo_Variable_List_Names_IDXs() local record, decoded_response, result decoded_response = Domo_Variable_List() result = decoded_response["result"] local variables = {} if result ~= nil then for i = 1, #result do record = result[i] if type(record) == "table" then variables[record["Name"]] = record["idx"] end end end return variables end
