Problem with setting up LightTable connection for tutorial

[kevinrobinson]

Not sure where the best place to post this, but figured I'd start here since having an awesome Om and ClojureScript tutorial experience is so important!

Following the tutorial, I add a connection to a Browser (External), grab the script tag, paste it inside the body tag of index.html. I opened the local file in Chrome, open web inspector, and refresh.

I don't see the XHR finished loading... message on the console, but I can see the request for ws.js succeeds and that code runs. I can also see the socket.io connection is opened successfully, with the init message is sent and heartbeat messages being set back and forth.

5:::{
  "name": "init",
  "args": [
    {
      "name": "localhost",
      "types": [
        "js",
        "css",
        "html"
      ],
      "commands": [
        "editor.eval.js",
        "editor.eval.cljs.exec",
        "editor.eval.html",
        "editor.eval.css"
      ]
    }
  ]
}

Being optimistic, and since I don't see a console.log in the ws.js code, I also tried to eval a line in core.cljs to update the atom as in the tutorial. When I try to evaluate with cmd+enter, LightTable UI looks like it's connecting:

(FWIW, I've used your awesome https://github.com/swannodette/lt-cljs-tutorial with no problems).

But then I get this error message in LightTable.

We couldn't connect.

Looks like there was an issue trying to connect to the project. Here's what we got:

Exception in thread "main" java.lang.RuntimeException: Unable to resolve var: cljs/*cljs-warn-on-undeclared* in this context, compiling:(lighttable/hub/clj/eval.clj:218:7)

Anyone experience anything similar, or have insight as to whether this is a LightTable bug or something I'm not setting up correctly here? Thanks!

It worked for me, I also was thrown off by not seeing the xhr message in the JS console. I didn't modify the code, just pasted the swap statement at the end of the file and cmd+entered it and it worked (after taking a minute to connect)

I clarified the XHR bit in the tutorial, the latter part is not something I've heard, probably best to take up with LT users.
