GKPlayer loadPhotoForSize: withCompletionHandler: Sandbox Connection Error - sandbox

I am trying to get avatars for game center friends using the loadPhotoForSize: withCompletionHandler: but it keeps throwing GKErrorDomain Code=3 "The requested operation could not be completed due to an error communicating with the server.
Does this method not work on Sandbox Game Center?

For me, it always gives this error if the player does not have a photo, but if I add a photo, the error goes away and it loads the photo correctly. I have only tested this in sandbox though, so I'm not sure if it works the same outside of sandbox.

Image inaccessible from python script but accessible in browser

I was trying to automatically download some traffic camera photos to play around with some image object recognition scripts and I have found that some links to them will throw a 403: Forbidden error when I try to download them from Python, and yet I can access them in a browser. One such image is at this link: https://www.svz-bw.de/kamera/ftpdata/KA101/KA101_gross.jpg
This code:
urllib.request.urlretrieve("https://www.svz-bw.de/kamera/ftpdata/KA101/KA101_gross.jpg", "traffic.jpg")
Returns a 403 error for me. What gives? I can understand that perhaps these organizations are not keen on having people bog down their servers with automatic downloads and perhaps there are some GDPR-related constraints, but I am actually more curious about how they are able to detect that the request is coming from a script and not from normal use

Nest REST API - unable to set structure to away

I've been using the same code for a few months now, then suddenly it decides to stop working. I searched through SO and Google and couldn't find an answer.
When I try to set nest to away using curl, I get this response back:
{"error":"Device is unable to service this request at this time"}
If I use the exact same code and just change the away value to home, it works fine, only setting it to away gives that error. I can also get and set the temperatures of all the devices without any problems.
This error response occurs when a device has been rate limited. Since setting home/away is at a structure level and affects all thermostats in your that structure. If any one thermostat is rate limited you will be blocked as indicated.
Are you sure you are able to control the thermostat temperature for all thermostats in that structure during the time that you are receiving this error?

Getting 409 error on form submit

So am getting a 409 Conflict with Failed to load resource error. Happens when i click on a form submit of a generic Java web application.
On click of the button there is no application log shows up, just the following error shows up and the process ends. This log is from browser console.
What are the possibilities for such an issue? Any help/suggestion will be really helpful.Help on internet was not much helpful.
Interestingly this is very intermediate i.e. it happens for a device and the next time you won't see it, comes back from grave again in few hrs or so.
Let me start by saying that I have not received this error, but based on your problem statement, it seems you could be having trouble with a file lock on your server. If you are attempting to call a resource that is loaded in another tool like an IDE, then it is possible the file is locked and the server is raising this error.
You may only receive this error if your server is in development mode vs production mode. Production mode will cache the file and not result in a conflict.
Here is a link that partially explains the problem.
HTTP Error 409 Conflict
Hope this helps!!

CouchDB app Toast won't load attachments

I'm learning CouchDB. I'm trying to load the example app Toast onto a local database and then take it apart to see how it works. The problem is that it isn't working, and I feel like the error is obvious but I just don't quite see it.
I've downloaded the development code from Github as a zip, extracted it into CouchDB/bin/toast, then used erica to push Toast onto my CouchDB. Here is my local Toast in Futon:
http://puu.sh/5hc2V.png
It appears to have been pushed correctly. However, when I navigate to http://127.0.0.1:5984/toast/_design/toast/index.html as erica instructs, I get this (with Chrome console):
http://puu.sh/5hc8X.png
I assumed the resources might be missing, but I checked, they are there both in the attachments for /vendor/ on CouchDB and in my file system from where erica pushed the application. Nonetheless, they do not appear to load.
What could be going wrong?
These resources should under _attachments, otherwise you'll get HTTP Error 404 Not found.

App-In purchase error -1001

II've been working on adding in-app purchases and was able to create and test in-app purchases using Store Kit.
Now I am unable to successfully complete any transactions and instead am getting only transactions with transactionState SKPaymentTransactionStateFailed.
The transaction.error.code is -1001 and the transaction.error.localizedDescription is "Cannot connect to iTunes Store"!
I have tried removing all products from iTunesConnect, and rebuilt them using different identifiers but that did not help. I have also tried using the App Store app to really connect to the real App Store and download some apps so I do have connectivity. Finally, I have visited the Settings:Store app to make sure I am signed out of my normal app store account.
you probably solved it by now but for others,
sometimes it takes time for apple to process new in app purchases. this is what the message -1001 actually saying
so, cross your fingers and wait for 24-48hours, dont change anything and you will probably be fine,
it will automatically start to work when they finish processing what is needed.
