Internal API errors are handled a few different ways depending on the type of error and the general exception handling patterns common to the platform. Some APIs use exceptions to manage errors. Error codes are documented here for reference, but for clarity refer to the specific API references for methods that throw exceptions or return error information. In most cases the API will defer error functionality to the objects and services available on the native platform. For example,
- Android/Java: in general, the API defers error functionality to ArcGISRuntimeException.
- iOS/macOS: in general, the API defers functionality to NSError.
- .NET: in general, the API defers error functionality to ArcGISRuntimeException.
- Qt: in general, the API manages error information using an Error object..
There are distinct classes of errors, depending on the service invoked. As the architecture dictates, errors may originate from the API, the runtime core supporting the API, or the service (the servers the API connects to implementing certain services.) Check the error domain if this is information useful to your app. In most cases you only need the error code to determine the cause of the error and possible remedy.
The API exposes several error domains. A domain is a segregated area of the API, usually bound to a framework, internal library, or module of functionality. The error domain helps focus the error to a specific area of functionality within the API.
There are different coding patterns used to handle errors that are specific to each API. Refer to the specific API documentation to understand how that API will communicate an error response. There are three patterns of error response:
Return codes: sometimes an API returns an error value or null. You test the return value and handle it according to your application implementation requirements.
Callback, lambda, or delegate function: certain APIs allow the caller to set an asynchronous callback function that the internal API calls upon certain defined events occurring. It is possible in these callbacks to receive an error. The API defines hows the error is represented in the callback. It is up to your application to handle the error.
Exceptions: some APIs generate an exception you should handle. There are many ways of receiving an exception: try/catch, error block/closure, error callback, or signal.
Error codes are defined here as integers. In order to safeguard your code from comparing against these numbers directly we suggest some form of abstraction, such as an errors enumeration or error class. We will do our best to never change a defined error code once the SDK is officially released, but we reserve the right to make changes. Please consult the release notes regarding any changes to these values.
API errors are client-side exceptions that usually occur due to incorrect method parameters, object state dependencies, or network conditions.
Invalid attributes or geometry on the associated GeoElement.
Null value is not allowed.
Value is out of range.
Value exceeds maximum field length.
Internal runtime errors are thrown by the core library when things go wrong client-side. Where possible the details of the exception are described. In many instances, the details of the exception are dependent on the context that generated the exception. In these cases, refer to the specific API that generated the error for more information.

Edit errors are returned by the server after you call apply edits on a service feature table. The EditError (EditError) object in the API wraps these error codes and messages. Refer to feature service error codes for more information.
HTTP, network, and REST errors
Some APIs communicate with servers and services over the World Wide Web using HTTP, such as the low-level REST API. These services may generate standard HTTP error codes that may have meaning related to the ArcGIS platform.

Authorization to the requested resource is required.
Authorization to the requested resource is required.
The requested resource was not found.

The request is larger than limits defined by the server. If you're trying to upload an attachment, this error might indicate that the attachment's size exceeds the maximum size allowed.
The access token provided is invalid or expired.
A token was required to access the resource.
The service was not able to fulfill the request, possibly due to invalid input, or the service may not be functioning properly.
The requested service is not implemented.
ArcGIS Runtime error Invalid access range Feature service is not loaded, it needs to be loaded before passed into the sync task.
Check that the offline data you're trying to access has been created correctly and make sure you understand the offline considerations described here.
A mobile geodatabase (.geodatabase file) must come either from an online feature service (from ArcGIS Online or ArcGIS Server 10.x) or be side loaded from content created by ArcGIS Desktop's Create Runtime Content tool. You can't manually create an offline mobile geodatabase. For details on creating and using a mobile geodatabase 1) in a service, see the services pattern 2) in the side loading pattern, see the desktop pattern.
A feature service must be sync-enabled if you want to edit it offline. Determine whether or not your service is sync-enabled by looking at the REST endpoint. A sync-enabled service has three specific REST endpoints listed at the bottom of its HTML page: 1) Create Replica 2) Synchronize Replica 3) Unregister Replica. For details on how to create a sync-enabled service on ArcGIS Online, see Managing hosted feature layers. Map services cannot be sync-enabled.
