Node.js and Server Sent Events

I had a problem with SSE as soon as I deployed my app on Heroku.

In the logs for the SSE there was this error:

Error: 500 RangeError: msecs must be a non-negative finite number
GET /live/redis 500 102.270 ms - -

In my route controller for /live/redis the first line was:

// let request last as long as possible
req.socket.setTimeout(Infinite);

I just copied it following a guide on the web but it was causing that error. So I changed it with this:

// let request last as long as possible
req.socket.setTimeout(0x7FFFFFFF);

Now it is working as expected but my question is: is it the correct way to solve this issue? There is a better parameter to pass in the setTimeout to be like Infinite?
