JWT Token response when trying to use API

I'm new to the API and I'm just trying to get a single API request to work. Right now, when I put the following API request, I get back my JWT Token as a response.
I've created a JWT and have the 3 headers set up with Content-type, Authorization, and zapiAccessKey.

I'm sending this request GET https://prod-api.zephyr4jiracloud.com/connect/public/rest/api/1.0/serverinfo

I get back my JWT token as a "response".

What am I missing here?
