The UI encounters an error when trying to display the preview data for a joiner plugin that has a field of type `bytes` in its output schema.
A screenshot of the error in the console is included in the attachments.

Fixed a bug in preview for fields that have non-string types such as bytes.
6.1.3 testing: Checked whether preview data renders for all stages in
with minified build.
