The requested resource is not found.

There’s a problem with an ongoing download or update: If an operation is in a paused state, you can resume or cancel it. If no operation is in a paused state: Either wait for active downloads to finish, or cancel existing sdk.maploader.MapDownloader requests and call sdk.maploader.MapDownloader.get_initial_persistent_map_status. If there is a problem, call sdk.maploader.MapDownloader.repair_persistent_map to repair before continuing with other sdk.maploader.MapDownloader operations. This error may occur when an on-going or paused operation prevents the requested task.

The request passed invalid arguments.

The request was cancelled (usually by the user).

All tiles of requested regions were already installed, no need for any download.

The request exceeded the timeout limit.

The requested service is unavailable.

The access is denied due to invalid credentials.

Request limit reached for set a credentials for a particular period of time.

A network connection error has happened.

The operation is forbidden, make sure your credentials grant the necessary permissions.

Downloaded map data is invalid or a sdk.maploader.RegionId passed to the method sdk.maploader.MapDownloader.delete_regions is incorrect.

Received unexpected response from the backend. It means the response is malformed or server returned an internal error. Try repeating the request.

Error occurred inside the map manager and might be related to network issues. Try repeating the request.

The data to process is incomplete, failed decoding the tile.

The conditions to access the service are not satisfied. Check if correct sdk.maploader.RegionId was passed to sdk.maploader.MapDownloader.download_regions or download for passed sdk.maploader.RegionId already started. Further control for started download must be performed through sdk.maploader.MapDownloaderTask.

Internal error occurred.

Online operation is not permitted because offline mode is enabled.

A cache IO error occurred.

Protected cache is corrupted. It can be a result of downloading the map in the background and the OS killing the application at that time. Use method sdk.maploader.MapDownloader.get_initial_persistent_map_status to get the status of the map and method repair_persistent_map in the MapDownloader to try to fix the cache if it is broken.

Operation on the protected cache cannot be done due to required migration. Call sdk.maploader.MapDownloader.repair_persistent_map to perform migration.

Method is invoked on object connected to the disposed SDKNativeEngine.

Misconfiguration of catalogs. This error may occur when sdk.core.engine.CatalogConfiguration is misconfigured and cannot be used for any operation with MapDownloader or MapUpdater. Verify SDKOptions.catalogConfigurations.

Map regions update was interrupted. Indicates that the cache state is wrong after an update that was finished not in correct way (e.g sudden app shutdown). Prefetching or removing of map regions are blocked until the update has been completed successfully.

Catalog update cannot proceed as another catalog update is in PENDING_UPDATE state. Update the catalog in PENDING_UPDATE state first, before trying to update another catalog.

Unrecoverable error during construction of pending update parameters. Operations such as catalog updates or region downloads will fail. The healing procedure is to clean persistent map with sdk.maploader.MapDownloader.clear_persistent_map_storage.

Parallel request is already running and conflicting with the current one (e.g updating map and deleting map regions)

Proxy is not authenticated. Check your proxy credentials.

Proxy server unreachable.

There’s no sufficient space on the disk to finish operation. For offline maps operation (download or update), it means that there’s not enough space on the device. For prefetch operations, it means that there’s not enough space in the mutable cache to store the prefetched data.

This version of HERE SDK does not support the ability to download maps. Contact the sales team to get access to the full version.
