[jira] [Commented] (NIFI-11156) ValidateXml Processor - validatexml.invalid.error = Validation failed

["David Handermann (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-11156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17686636#comment-17686636 ] 

David Handermann commented on NIFI-11156:
-----------------------------------------

Thanks for describing this issue [~bilalb].

Changes to the content of the {{validatexml.invalid.error}} attribute were introduced as a result of generalized XML processing improvements in NIFI-9901.

The generalized "Validation failed" message comes from the {{ProcessingException}} thrown in {{StandardSchemaValidator}}. To provide more details in the error attribute, an ideal solution would walk through the exception causes and build up the string of messages. That should allow {{StandardSchemaValidator}} to remain unchanged, and also provide the expected details in this error attribute value.

> _NiFi_ environment was upgraded from 1.15.1 to 1.19.1. The following situation has occurred with the _ValidateXml_ processor:
> _ValidateXml_ processor works correctly on 1.15.1 and _validatexml.invalid.error_ attribute gives an detail information about the error.
> _ValidateXml_ processor works on 1.19.1 but _validatexml.invalid.error_ attribute does not give an detail information about the _error. validatexml.invalid.error_ attriubute only contains “{_}Validation failed{_}” text.
> Similar problem was talked in cloudera community and Eduu said that:

> Hi [@ChuckE|https://community.cloudera.com/t5/user/viewprofilepage/user-id/98065] using NiFi 1.15.2 seems to add the error detail in the "validatexml.invalid.error" attribute.
> For example --> "cvc-minLength-valid: Value '' with length = '0' is not facet-valid with respect to minLength '1' for type 'HotelCode"
> This seems to be an issue starting from NiFi 1.16.3, maybe a bug?
> You can use NiFi 1.15.2 or custom code as [@SAMSAL|https://community.cloudera.com/t5/user/viewprofilepage/user-id/80381] suggested.
