Later on, I found that I need to upgrade the version of Postman. Stratis Blockchain Full Node Swagger.json file is not recognized as a valid format if we use the older version of Postman. So, the solution to this issue is to upgrade the Postman from the lower version to the upper one. I upgraded to version 8.7.0, and I was able to import the Swagger.json file without any issue.
