I am having this issue, can someone please take a look and let me know what I could possibly have done wrong? I already checked for all the spellings and potential hidden special characters, I will attach some more references in the comment sections


SOLVED - leaving this here for anyone with similar issues, it looks like my setup for preview in the referenced type is wrong, I fixed it and it is working now
