IllegalArgumentException when the http response return duplicated header.

    Description

      I got the IllegalArgumentException with a simple HTTP request using the tacokit HTTP client.
      And the error message really confused me. After debugging and checking with the postman. I found that the duplicate header key causes the problem. "X-Request-Id" and "X-Request-ID" which only different in cases. They did not pass the merge check, but the error message gives the value rather than the KEY.
