If the Proxy Adds a Header in the Tunnel, it Doesn't Show Up at the Endpoint

See the discussion by @huzaifamk on June 5, 2024 on Discord regarding this issue. I too have face the issue.

If you look at the initializeECDHTunnel in the interceptor:

            Respbody := utils.ReadResponseBody(resp.Body)

            data := map[string]interface{}{}

            err = json.Unmarshal(Respbody, &data)
            if err != nil {
                reject.Invoke(js.Global().Get("Error").New("The data received from the proxy could not be unmarshalled: ", err.Error()))
                EncryptedTunnelFlag = false
                return
            }

            UpJWT = data["up-JWT"].(string)

            server_pubKeyECDH, err := utils.JWKFromMap(data)
            if err != nil {
                reject.Invoke(js.Global().Get("Error").New(err.Error()))
                EncryptedTunnelFlag = false
                return
            }

We weren't able to but the up-JWT in the headers....

To recreate the issue, try adding extra headers to the request coming from the Middleware on it's return trip to the Interceptor. The header is missing.
