FreeFormTextWriter and flowfiles attributes

Hello.

FreeFormTextWriter is not reading the flowfile attributes when using ${}. I've try
${attributename} and ${anyAttribute('attributename')} but both fails silently and always return null (isNull is always true).

Can FreeFormTextWriter access attributes, or do I have to updateRecord with the attribute I want?

Thanks.

As Bryan said, it was not intended to provide access to FlowFile Attributes. There is, however, a Jira [1] to add this capability.

Thanks

FreeFormTextWriter allows you to use expression language to reference
fields in the record, so ${field1} ${field2} where field1 and field2
are part of the record.

If you are trying to access attributes then I think you need to use
UpdateRecord first.
