THEN Merge sessionId and requestInit into a single second argument options object. The constructor expects two arguments: URL and an options object that includes both sessionId and requestInit properties. Do not pass sessionId as a separate argument.

// Incorrect: three arguments
const transport = new StreamableHTTPClientTransport(
  new URL(serverUrl),
  { sessionId: sessionId },
  { requestInit: { headers: { Authorization: 'Bearer ' + token } } }
);

// Correct: two arguments with all options in second argument
const transport = new StreamableHTTPClientTransport(
  new URL(serverUrl),
  {
    sessionId: sessionId,
    requestInit: {
      headers: { Authorization: 'Bearer ' + token }
    }
  }
);
