NIFI-15809 Record path toBytes returns an ARRAY[BYTE] type (#11121)
The toBytes function previously returned a FieldValue that inherited
the source field's DataType instead of ARRAY[BYTE]. This caused type
mismatches when the source field was a string.
> Invalid output field type in ToBytes record path function

> Key: NIFI-15809
> URL: https://issues.apache.org/jira/browse/NIFI-15809
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 2.8.0
> Reporter: Alaksiej Ščarbaty
> Assignee: Alaksiej Ščarbaty
> Priority: Major
> Fix For: 2.10.0

> Time Spent: 0.5h

>
> The {{toBytes()}} RecordPath function preserves the source field's data type
> (e.g., STRING) on the returned {{FieldValue}} instead of using ARRAY.
> When used with {{UpdateRecord}} to write the field, the destination field
> inherits the source's type, which is incorrect.
> The output fields should always be of a ARRAY type.
