Swag: Fetch error Internal Server Error doc.json

[rafi73]

Describe the bug
I've followed the procedure to use swag with a gin application. I've also checked the example implementation from the source. But, unfortunately facing the error. I'm attaching 2 screenshots of the problem.

To Reproduce
Steps to reproduce the behavior:

1. go get -u github.com/swaggo/swag/cmd/swag
2. Follow the steps to use it with gin application.
3. After doing swag init, I faced a problem like swag not found on a mac. So I did export PATH=$PATH:$HOME/go/bin which fixed the error and generated required files in ./docs dir.
4. After running the application, I used http://localhost:8888/swagger/index.html as url and getting this error.

Expected behavior
I wanted to display the API docs.
