HTTP operation cancelled

Recommended Posts

Hello guys


I need some hepl from anyone outthere..


I am using a QA to send text to Raspberry and play it on Google nest speakers. This was working like a charm until yesterday, and i swear I didn't touch a single line of code.

From yesterday i am getting error i http response "Operation cancelled"

I need some experienced propgrammer to check on this, becuse it's way beyond my comprehension, how can something be working for long time, and suddenly stop working from out of the blue.


I am really thankfull for any suggestion.



This is the http call i am using



        requestStr = {text = message_to_sent, targetip = nest_ip, volume = nest_volume, language = nest_language} -- storign data in JSON string format
        requestTringToJSON = json.encode(requestStr)  -- making JSON string from the string
        local http = net.HTTPClient({timeout=6000,})
            http:request(self.raspberry_ip..request_command, {
                    headers = {['Accept'] = "application/json", ['Connection']='keep-alive',['Content-Type']='application/json' },
                    method = 'POST',
                    data = requestTringToJSON -- sending data in JSON string format
            success = function(status)
            error = function(error)
                self:debug('error: ' .. json.encode(error))

  • I didn't change anything. Thanks anyway for help.

    Someone can explain me what can cause this?


    If I left out the complete  headers = {['Accept'] = "application/json", ['Connection']='keep-alive',['Content-Type']='application/json' }, line than it starts to work.


    If I had it in there, i am getting in Raspberry "Unexpected token o in JSON at position 1", but the JSON is the same as it was moths ago..i changed nothing, i am sending a simple text. SO without the header it works, I dont know how long, but now it works without the complete header part.


    and i didn't touch anyithing, neither in Raspberry nor in PC..This is driving me crazy
