Inserting the "{" in the URL of a request crashes

[jwbanning]

Describe the bug
I am trying to change a URL from http://example.com to use an environmental var. The syntax should be the double curly bracket "{{ }}". When I go to modify the request string in the application, inserting the "{" makes the app fail.

Expected behavior
The environmental variable or curly brackets would be allowd.
