------------------------------------
Summary: Flow file attributes can break UnpackContent using
flowfile-tar-v1 format
Key: NIFI-5328
URL: https://issues.apache.org/jira/browse/NIFI-5328
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.6.0
Reporter: Joseph Gresock
I'm using NiFi to MergeContent using flowfile-tar-v1 format, followed by
UnpackContent with the same format. One of my flow files has an attribute with
the following value:
{code:java}
Unrecognized token 'PKI': was expecting
('true', 'false' or 'null')
at [Source: (StringReader); line: 1, column: 12]{code}
I can view the resulting tar on disk, and it is formatted correctly. However,
the UnpackContent processor gets the following error, apparently caused by
trying to dereference XML entities from the attribute value:
