Hello! I’m trying to call a basic cloud function I added to my INO file. For simplicity’s sake, I’ve commented everything else out in the code except the call to `Spark.function()` and the function itself, which simply returns 1. Following the exact curl in the examples, I continuously get: `{ "ok": false, "error": "Timed out." }` I’m down to the most basic example I can get. Any ideas on where I should start debugging? I’m running `curl https://api.spark.io/v1/devices// -d access_token= -d "args=1"`. ---

Where did you add the `Spark.function()` to `setup()`? ---

Posting the code you are flashing to your core would be of great help. Would you minding doing so when you reply? ---

One other thing that comes up a lot is that Spark.function names are limited to 12-characters and get truncated so that when you use curl to call the longer name you think you have, you see this error. You can use a GET request to find the actual name or just check your code. ---

Ah - it turns out `setBrightness` is 13 characters, which is what did it. A few recommendations: - You mention the 12 character limit on the `Core Code (Firmware)` page, but not on `Cloud Code (API)`, which is where people will be when they’re actually trying to call a function. It would be great to get a mention of the limit added to the `CONTROLLING A CORE` section. - From a technical perspective, a 10 second timeout when a method name is not found is a relatively bad developer experience. You’re much more familiar with your systems than I am, but having the Core return a “Not Found” error (or maintaining a server side index of functions that are enabled, since the Core in question must be on the Internet to receive a function request in the first place, and catching it at the API layer) would be extremely helpful. Thanks for your help! ---

Glad it is working for you now. Your other remarks are best directed to Spark staff – perhaps @Dave can capture this request for the cloud to improve. ---

Hey @mvd7793, you can always do a GET to [https://api.spark.io/v1/devices/DEVICE\_ID/?access\_token=ACCESS\_TOKEN](https://api.spark.io/v1/devices/DEVICE_ID/?access_token=ACCESS_TOKEN) to get a list of active function on a core. I do agree however, a 10 second timeout is a little long. It would also be nice if the WEB IDE checked spark.function calls for names longer than 12 characters. @mvd7793, I have added a pull request for the spark docs ([https://github.com/spark/docs/pull/250](https://github.com/spark/docs/pull/250)). Would that additional have helped you?
