SockJsClient authentication headers

Hello, I have question about authentication header adding while subscribing to server.

I am trying to do it like this:

       <SockJsClient url={ wsSourceUrl } topics={[this.state.channelId]} headers={"Authorization: `Bearer ${this.token}`"}
          onMessage={ this.onMessageReceive } ref={ (client) => { this.clientRef = client }}
          onConnect={ () => { this.setState({ clientConnected: true }) } }
          onDisconnect={ () => { this.setState({ clientConnected: false }) } }
          debug={ false }/>

But Header isn’t getting set. What I am doing wrong?

@lahsivjar, it was problem in my CORS configuration. Thank you for your patience 😃 Headers works well.

@Prasad-YS How did your solve it? I have the exact same problem, headers don’t even show up on the request.
