Why do I get an 404 error when fetching profile-images?

You wrote the "404" results prevents your application from "graduating" but the API url you posted is the url for production environment (https://platform.ringcentral.com/restapi/v1.0/account/~/extension/803791067) Using the .Net SDK on sandbox environment, you need to set the correct platform when creating the SDK instance. I.e 'https://platform.**devtest**.ringcentral.com'

@Phong Vu Thanks. Yes, you can disregard my comments about "graduating". Because I was getting the "404" errors, it did (past tense) stop us graduating. So I remove the "fetching images" bit from our code. As a result the application then passed (graduated) and hence I then went on to documente the problem on the production environment. The problem is still happening. I can't seem to get the images using the SDK, on the Sandbox or on Production. Does "404" signify that the user supposedly has no picture? If so, it's a shame that it returns an error ("404") and not something nicer, like a "204 No Content".

Hi @Phong Vu Thanks again. I have added the new traces below. I'm not really sure about your second comment. Could this be why the problem is now happening? The same code used to work when it was written. I created and registered the app using the first (trial) account. But then as you say, I have got a new, different production account. I thought I would carry on using the first account as just like a "developer" account, that I only accessed to edit/publish the app. And I'd use my new account for real calls, etc. Is that now how it works? Should I move/recreate the app under my new account?
