Hey @sumabala9
Welcome to the community!!
You’re running that newman command from the npm directory, which contains a newman directory and because you’re using a reporter, it creates a newman directory by default to add the report too and it’s clashing with this - Try running the same command from a different directory and see if that works.
You could also use the --reporter-html-export report.html flag to create a file but I would recommend just running the full command away from the npm directory.
The command doesn’t look quite right either, I would have expected the collection to be a .json or a URL.
Also, you really should be using htmlextra
