Shouldn't this say `"Argument supplied to base64Decode must be a String"`
(instead of `base64Encode`)?
> RecordPath Language should allow base64 encode and decode
> ---------------------------------------------------------

> Key: NIFI-5449
> URL: https://issues.apache.org/jira/browse/NIFI-5449
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Dalibor Frívaldský
> Assignee: Matt Burgess
> Priority: Minor
>
> Currently there is no way to encode/decode a record field using base64
> encoder/decoder. Without this functionality it is, for example, impossible to
> store data into databases that require base64 representation of varbinary
> values (e.g. Apache Phoenix).
