@Anil Sagar, @whitman zhang. Thank you for the reply. I could not provide actual contents in the swagger due to security issue. I have just replaced actual content to sample.
can you please de-face the security-related data in your .json file and maybe trim it down to a minimal reproducible datagram, ie., remove part of the documents until you can still replicate your problem.
Actually, It works when I remove the tags from the JSON file. And It worked when I convert same file into YAML along with tags. Got Surprised. Not sure what is going wrong in the JSON file. As mentioned by @whitman zhang, I have removed “,” at the end of tags. Still same issue.
