# Generic Error Handling

The SDK launch always returns a result. The result may be negative and contain an error.

The iOS SDK has generic errors that provide feedback to the integrator about why the process was stopped.

#### Common - Basic

General states that do not fall into a specific functional category.

* `.NO_ERROR`: Default state; indicates that the operation completed without issues.
* `.UNKNOWN_ERROR`: An error has occurred that has not been identified or specifically categorized.
* `.OTHER(String)`: Generic error for cases not covered. Includes a custom message via a `String`.

#### Common - Requirements

Errors related to data availability, process lifecycle, or connectivity.

* `.NO_DATA_ERROR`: The process needs a configuration value that has not been provided correctly or is null.
* `.OPERATION_NOT_CREATED`: The operation could not be initialized correctly.
* `.NETWORK_CONNECTION`: Communication error; the device has no internet access or the server does not respond.

#### Common - Permissions

They are triggered when the user or the operating system denies access to hardware or files.

* `CAMERA_PERMISSION_DENIED`: Access to the device camera was blocked.
* `MIC_PERMISSION_DENIED`: Access to the microphone was blocked.
* `LOCATION_PERMISSION_DENIED`: Location services (GPS) are not authorized.
* `STORAGE_PERMISSION_DENIED`: Read/write permission on local storage was denied.

#### Common - User Interaction

Errors resulting from user behavior or session restrictions.

* `CANCEL_BY_USER`: The process was explicitly canceled by the user.
* `SDK_TIMEOUT`: The capture process exceeded the configured maximum wait time.

#### Common - License Errors

Validation errors related to the license key or the SDK components.

* `.LICENSE_CHECKER_ERROR(String)`: General error during license validation with the server. The parameter `String` indicates the detail more explicitly.
* `.MISSING_COMPONENT_LICENSE_DATA`: The component being launched needs data that has not been configured correctly in the license.
* `.COMPONENT_LICENSE_ERROR`: The component being used is not enabled in the license.
* `.EMPTY_LICENSE`: The license field is empty.

**In addition to the generic ones, each module may contain specific errors that will be detailed on their respective documentation pages.**
