At the moment the Assets import logs print an exception where a unique constraint on an attribute set as unique is violated but they do not print which item value is violating it.

Ex.

• an attribute serial number is set as unique
• the import source try to import a serial number which already exists in another object in the object type
• following exception is thrown out:

Error messages: context: rlabs-insight-attribute-5762; messages: [ErrorMessage {i18nKey='rlabs.insight.i18n.constraint.violation.unique', parameters=[Name of the attrribute], additionalMessage=null}

As above example the error report the cause and the attribute name but not the actual value which cannot be duplicated.

Adding the offending value as well would make a research quite more easier.
