docs: Returns a full representation of the issue for the given issue key.
  
          The issue JSON consists of the issue key and a collection of fields. Additional information like links to
          workflow transition sub-resources, or HTML rendered values of the fields supporting HTML rendering can be
          retrieved with expand request parameter specified.
  
          The fields request parameter accepts a comma-separated list of fields to include in the response. It can be used
          to retrieve a subset of fields. By default all fields are returned in the response. A particular field can be
          excluded from the response if prefixed with a "-" (minus) sign. Parameter can be provided multiple times on a
          single request.
  
          By default, all fields are returned in the response. Note: this is different from a JQL search - only navigable
          fields are returned by default (*navigable).
