How would I render this type of example out in a Gutenberg block, https://metabox.io/clone-group-custom-fields-using-meta-box-group/
I have tried a number of different ways and am totally stumped. I can render the fields out in the right sidebar and can add more fields etc, but when I try and populate the fields I get a loader in the Gutenberg block and no content.
I have also tried the code from https://support.metabox.io/topic/block-doesnt-render-on-frontend/ . I know that the template file to display the content works in that it outputs the first line -> echo 'test output';, but it throws an error for any data that I enter into the clonable fields saying that the JSON is incorrect.
If anyone could help using this example with the cars https://metabox.io/clone-group-custom-fields-using-meta-box-group/ to output the content from the fields in the actual Gutenberg block I would be massively appreciative.
Many thanks in advance,
