Variable not found!

Troubleshooting
1

Hi Guys，I am using my Spark Photon to do some test.The setup code is as below

void setup()
{
  char addr[16];

  Serial.begin(115200);
  delay(2000)

  IPAddress localIP = WiFi.localIP();

  while (localIP[0] == 0)
  {
    localIP = WiFi.localIP();
    Serial.println("waiting for an IP address");
    delay(1000);
  }


  Serial.print(localIP[0], DEC);
  Serial.print('.');
  Serial.print(localIP[1], DEC);
  Serial.print('.');
  Serial.print(localIP[2], DEC);
  Serial.print('.');
  Serial.println(localIP[3], DEC);

  server.begin();

  //Setup the Tinker application here

  //Register all the Tinker functions

  Spark.variable("getjson",json_tx_string,STRING);
  Spark.function("digitalread", tinkerDigitalWrite);
  Spark.function("digitalwrite", tinkerDigitalWrite);
  Spark.function("analogread", tinkerAnalogRead);
  Spark.function("analogwrite", particleToDuo);

}

before I changed the variable key to “getjson” , it was “mess” and it will return the right message when I use the url https://api.particle.io/v1/devices/xxx/mess?access_token=xxx

but after I changed it ,I got the message as{“ok”: false,“error”: “Variable not found”}when I used https://api.particle.io/v1/devices/xxx/getjson?access_token=xxx

even I changed the key back ,it couldn’t recover anymore. I just don’t know why!!!

Could you try putting the variables/functions at the top of the setup? Too long delays might cause them to not ‘take’.
As a tool, you could use this page to check which functions/variables are available.

I’ve tryed but it just not worked

If you’ve got some code I can copy&paste, then I can test it.

the problem disappears now but I don’t know why, maybe is the cloud is unstable
