The decode_base64_field processor specifies a field to base64 decode. The field key contains a from: old-key and a to: new-key pair. from is the origin and to the target name of the field.

To overwrite fields either first rename the target field or use the drop_fields processor to drop the field and then rename the field.

processors:
  - decode_base64_field:
      field:
        from: "field1"
        to: "field2"
      ignore_missing: false
      fail_on_error: true

In the example above: - field1 is decoded in field2

The decode_base64_field processor has the following configuration settings:
