`invalidParameterValue`	-2003	One of the given parameter(s) has an invalid value.
`invalidPixelFormat`	-2004	The image pixel format is invalid.
`invalidTemplateFormat`	-2005	The template format is invalid.
`invalidResolution`	-2006	The image resolution is invalid.
`invalidFingerPosition`	-2007	The finger position associated with the Image/Template is invalid.
`invalidFilePath`	-2008	The given file path could not be found/opened.
`unloadedModel`	-2020	The model which is required for this operation was not loaded.
`processingUnitUnavailable`	-2039	The requested processing unit is not available in this build.
`inferenceBackendError`	-2040	The inference backend failed to infer, probably due to inconsistent input.
`moduleBusy`	-2041	This module is currently used by another thread.
`notSupportedAn2kTransaction`	-2042	This ANSI/NIST-ITL 1:2011 transaction cannot be loaded in a finger image record.
`backendError`	-2043	An error happened in the algorithmic backend.
`indexerAlreadyInitialized`	-2050	The finger indexer object is already initialized.
`indexerIdAlreadyExists`	-2051	The requested ID already exists in the finger indexer object.
`indexerInvalidTemplateData`	-2052	The data of the template is corrupted and cannot be added to the finger indexer object.
`indexerFull`	-2053	Maximum size of the finger indexer object has been reached.
