Device Update for IoT Hub error codes

Article
01/16/2024

This document provides a table of error codes for various Device Update components.

There are two primary client-side components that may throw error codes: the Device Update agent, and the Delivery Optimization agent. Error codes also come from the Device Update content service.

Device Update agent

ResultCode and ExtendedResultCode

The Device Update for IoT Hub Core PnP interface reports ResultCode and ExtendedResultCode, which can be used to diagnose failures. For more information about the Device Update Core PnP interface, see Device Update and Plug and Play. For more details regarding the default meanings of Device Update agent ResultCode and ExtendedResultCodes, see the Device Update GitHub repository.

ResultCode is a general status code and ExtendedResultCode is an integer with encoded error information.

The ExtendedResultCode appears as a signed integer in the PnP interface. To decode the ExtendedResultCode, convert the signed integer to unsigned hex. Only the first 4 bytes of the ExtendedResultCode are used and are of the form F FFFFFFF where the first nibble is the Facility Code and the rest of the bits are the Error Code.

Facility Codes

Facility Code	Description
D	Error raised from the DO SDK
E	Error code is an errno

For example:

ExtendedResultCode is -536870781

The unsigned hex representation of -536870781 is FFFFFFFF E0000083.

Ignore	Facility Code	Error Code
FFFFFFFF	E	0000083

0x83 in hex is 131 in decimal, which is the errno value for ENOLCK.

Delivery Optimization agent

The following table lists error codes pertaining to the Delivery Optimization (DO) component of the Device Update client. The DO component is responsible for downloading update content onto the IoT device.

The DO error code can be obtained by examining the exceptions thrown in response to an API call. All DO error codes can be identified by the 0x80D0 prefix.

Error Code	String Error	Type	Description
0x80D01001L	DO_E_NO_SERVICE	n/a	Delivery Optimization was unable to provide the service
0x80D02002L	DO_E_DOWNLOAD_NO_PROGRESS	Download Job	Download of a file saw no progress within the defined period
0x80D02011L	DO_E_UNKNOWN_PROPERTY_ID	Download Job	SetProperty() or GetProperty() called with an unknown property ID
0x80D02012L	DO_E_READ_ONLY_PROPERTY	Download Job	Unable to call SetProperty() on a read-only property
0x80D02013L	DO_E_INVALID_STATE	Download Job	The requested action isn't allowed in the current job state. The job might have been canceled or completed transferring. It is in a read-only state now.
0x80D02018L	DO_E_FILE_DOWNLOADSINK_UNSPECIFIED	Download Job	Unable to start a download because no download sink (either local file or stream interface) was specified
0x80D02200L	DO_E_DOWNLOAD_NO_URI	IDODownload Interface	The download was started without providing a URI
0x80D03805L	DO_E_BLOCKED_BY_NO_NETWORK	Transient conditions	Download paused due to loss of network connectivity

   0 00 00000     Total 4 bytes (32 bits)
   - -- -----
   | |  |
   | |  |
   | |  +---------  Error code (20 bits)
   | |
   | +------------- Component/Area code (8 bits)
   |
   +--------------- Facility code (4 bits)

For more information about parsing codes, see Device Update Agent result codes and extended result codes or implement a custom Content Handler.

Device Update content service

The following table lists error codes pertaining to the content service component of the Device Update service. The content service component is responsible for importing update content. More troubleshooting information is also available for importing proxy updates.

Error code	String error	Next steps
UpdateAlreadyExists	Update with the same identity already exists.	Make sure you're importing an update that hasn’t already been imported into this instance of Device Update for IoT Hub.
DuplicateContentImport	Identical content imported simultaneously multiple times.	Make sure you're importing an update that hasn’t already been imported into this instance of Device Update for IoT Hub.
CannotProcessImportManifest	Error processing import manifest.	Refer to import concepts and import update documentation for proper import manifest formatting.
CannotDownload	Cannot download import manifest.	Check to make sure the URL for the import manifest file is still valid.
CannotParse	Cannot parse import manifest.	Check your import manifest for accuracy against the schema defined in the import update documentation.
UnsupportedVersion	Import manifest schema version is not supported.	Make sure your import manifest is using the latest schema defined in the import update documentation.
Error importing update due to exceeded limit.	Cannot import additional update provider.	You've reached a limit on the number of different providers allowed in your instance of Device Update for IoT Hub. Delete some updates from your instance and try again.
Error importing update due to exceeded limit.	Cannot import additional update name for the specified provider.	You've reached a limit on the number of different names allowed under one provider in your instance of Device Update for IoT Hub. Delete some updates from your instance and try again.
Error importing update due to exceeded limit.	Cannot import additional update version for the specified provider and name.	You've reached a limit on the number of different versions allowed under one provider and name in your instance of Device Update for IoT Hub. Delete some updates with that name from your instance and try again.
Error importing update due to exceeded limit.	Cannot import additional update provider with the specified compatibility. or Cannot import additional update name with the specified compatibility. or Cannot import additional update version with the specified compatibility.	When defining compatibility properties in an import manifest, keep in mind that Device Update for IoT Hub supports a single provider and name combination for a given set of compatibility properties. If you try to use the same compatibility properties with more than one provider/name combination, you'll see these errors. To resolve this issue, make sure that all updates for a given device (as defined by compatibility properties) use the same provider and name.
CannotProcessUpdateFile	Error processing source file.
ContentFileCannotDownload	Cannot download source file.	Check to make sure the URL for the update file(s) is still valid.
SourceFileMalwareDetected	A known malware signature was detected in a file being imported.	Device Update for IoT Hub scans imported content for malware using several different mechanisms. If a known malware signature is identified, the import fails and a unique error message is returned. The error message contains the description of the malware signature, and a file hash for each file where the signature was detected. You can use the file hash to find the exact file being flagged, and use the description of the malware signature to check that file for malware. Once you have removed the malware from any files being imported, you can start the import process again.
SourceFilePendingMalwareAnalysis	A signature was detected in a file being imported that may indicate malware is present.	Device Update for IoT Hub scans imported content for malware using several different mechanisms. The import fails if a scan signature has characteristics of malware, even if there isn't an exact match to known malware. When this occurs, a unique error message is returned. The error message contains the description of the suspected malware signature, and a file hash for each file where the signature was detected. You can use the file hash to find the exact file being flagged, and use the description of the malware signature to check that file for malware. Once you've removed the malware from any files being imported, you can start the import process again. If you're certain your files are free of malware and continue to see this error, use the Contact Microsoft Support process.
