Model Conversion Error Codes

For common modes of model conversion failure, the Azure.MixedReality.ObjectAnchors.Conversion.AssetConversionProperties object obtained from the Value field in the Azure.MixedReality.ObjectAnchors.Conversion.AssetConversionOperation contains an ErrorCode field of the ConversionErrorCode type. This type enumerates these common modes of failure for error message localization, failure recovery, and tips to the user on how the error can be corrected.

Error Code	Description	Mitigation
INVALID_ASSET_URI	The asset at the URI provided when starting the conversion job could not be found.	When triggering an asset conversion job, provide an upload URI obtained from the service where the asset to be converted has been uploaded.
INVALID_JOB_ID	The provided ID for the asset conversion job to be created was set to the default all-zero GUID.	If a GUID is specified when creating an asset conversion job, ensure it is not the default all-zero GUID.
INVALID_GRAVITY	The gravity vector provided when creating the asset conversion job was a fully zeroed vector.	When starting an asset conversion, provide the gravity vector that corresponds to the uploaded asset.
INVALID_SCALE	The provided scale factor was not a positive non-zero value.	When starting an asset conversion, provide the scalar value that corresponds to the measurement unit scale (with regard to meters) of the uploaded asset.
ASSET_SIZE_TOO_LARGE	The intermediate .PLY file generated from the asset or its serialized equivalent was too large.	Refer to the asset size guidelines before submitting an asset for conversion to ensure conformity.
ASSET_DIMENSIONS_OUT_OF_BOUNDS	The dimensions of the asset exceeded the physical dimension limit. This can be a sign of an improperly set scale for the asset when creating a job.	Inspect the ScaledAssetDimensions property in your AssetConversionProperties object: it will contain the actual dimensions of the asset that were calculated after applying scale (in meters). Then, refer to the asset size guidelines before submitting an asset for conversion to ensure conformity, and ensure the provided scale corresponds to the uploaded asset.
ZERO_FACES	The intermediate .PLY file generated from the asset was determined to have no faces, making it invalid for conversion.	Ensure the asset is a valid mesh.
INVALID_FACE_VERTICES	The intermediate .PLY file generated from the asset contained faces that referenced nonexistent vertices.	Ensure the asset file is validly constructed.
ZERO_TRAJECTORIES_GENERATED	The camera trajectories generated from the uploaded asset were empty.	Refer to the asset guidelines before submitting an asset for conversion to ensure conformity.
TOO_MANY_RIG_POSES	The number of rig poses in the intermediate .PLY file exceeded service limits.	Refer to the asset size guidelines before submitting an asset for conversion to ensure conformity.
SERVICE_ERROR	An unknown service error occurred.	Contact a member of the Object Anchors service team if the issue persists: https://github.com/Azure/azure-object-anchors/issues
ASSET_CANNOT_BE_CONVERTED	The provided asset was corrupted, malformed, or otherwise unable to be converted in its provided format.	Ensure the asset is a validly constructed file of the specified type, and refer to the asset size guidelines before submitting an asset for conversion to ensure conformity.

Any errors that occur outside the actual asset conversion jobs will be thrown as exceptions. Most notably, the Azure.RequestFailedException can be thrown for service calls that receive an unsuccessful (4xx or 5xx) or unexpected HTTP response code. For further details on these exceptions, examine the Status, ErrorCode, or Message fields on the exception.

Exception	Cause
ArgumentException	Occurs when using an invalidly constructed or all zero account ID to construct a request with the ObjectAnchorsConversionClient. Occurs when attempting to initialize the ObjectAnchorsConversionClient using an invalid whitespace account domain. Occurs when an unsupported service version is provided to the ObjectAnchorsConversionClient through ObjectAnchorsConversionClientOptions.
ArgumentNullException	Occurs when attempting to initialize the ObjectAnchorsConversionClient using an invalid null account domain. Occurs when attempting to initialize the ObjectAnchorsConversionClient using an invalid null credential.
RequestFailedException	Occurs for all other issues resulting from a bad HTTP status code (unrelated to the status of a job that will/is/has run), such as an account not being found, an invalid upload uri being detected by the fronted, frontend service error, etc.
UnsupportedAssetFileTypeException	Occurs when attempting to submit a job with an asset with an extension or specified filetype that is unsupported by the Azure Object Anchors Conversion service.
