Path parameter accepting curly braces in the value but doesn't show up in curl command

[#1]

Hi All,

We have one API published on developer portal which has a path parameter in it.

In the path parameter if we are giving curly braces in the value then it removes those curly braces while calling the API. I do not see any curly braces in curl command or request made.

Following image will give more clarity on the issue.

I was wondering why it is happening?? Is this kind of default behavior of developer portal??

Please help.
