Realm Object Server - Error: Your request parameters did not validate

Question

I built a small iOS application which uses Realm instead of CoreData. The app does not require a login as it only stores data entered by the user. I'm currently trying to save users data so that if a user deleted the app for example, the data will be there by default the next the app is re-installed.

Here's where I am getting confused. Can I still use Realm Mobile Platform even though the app will not require a login screen. (i.e. data will automatically be saved for users who are logged-in to their iCloud accounts).

Here's what I've done so far:

1. I configured Realm Object Server on an AWS EC2 instance, and I can login to the realm dashboard through the browser just fine.
2. I configured the cloudKit stanza in the configuration.yml file as per the authentication instructions.

3. In my setupRealm() func, I tried the following code but I keep getting a parameters validation error:

   SyncUser.logIn(with: cloudKitCredentials,
                  server: serverURL) { user, error in
                   if let user = user {
                       print("in")
                   }
   
                   else if let error = error {
                       fatalError(String(describing: error))
                       // Error: "Your request parameters did not validate."
                   }
   

   This is the error message:

   Error Domain=io.realm.sync Code=3 
   "Your request parameters did not validate." 
   UserInfo={statusCode=400, 
             NSLocalizedDescription=Your request parameters did not validate.}:
   

I suspect that the my iCloud user is not being tied with the object server, but I can't seem to put the pieces together. I'd appreciate any pointers.

Answer 1

The server requires a restart after editing the authentication lines in the configuration.yml.
