Troubleshooting

Accessing source maps

Update your configuration to include unstable.minify = false and unstable.dump_build = true.

{
	"builds" {
		"counter" {
			"script": "counter.ts",
			"access": "public",
			"unstable": {
				"minify": false,
				"dump_build": true
			}
		}
	}
}

rivet.json

Tip

unstable.minify = false is not required, but it maintains symbol names & whitespace to make your backtraces easier to read.

After you deploy again, you'll see a new line in your output:

$ rivet deploy
...etc...
[Build Path] /var/folders/hh/qn66rcl906gg79xjk27qhg900000gn/T/.tmpX5Jcer
...etc...

Command Line

Inside the build folder printed above (e.g. /var/folders/hh/qn66rcl906gg79xjk27qhg900000gn/T/.tmpX5Jcer), you'll find both:

index.js The file that's running on the server. You can manually look up your backtraces in this file.
index.js.map The source map for your code. You can look up the backtrace in this

Resolving a location in the source map

To look up the location file:///index.js:3754:17, you can:

cd to the build path (see above)

Run:

$ npx source-map-cli resolve index.js.map 3754 17
Maps to ../../../../../../Users/nathan/rivet/ee/oss/examples/counter/counter.ts:39:14

    console.log(new Error("foo"));
            ^

Command Line

`Bad Gateway` when making request to actor

This indicates that your actor's HTTP server is:

Not responding to requests
Is respondign with invalid data
Your actor is crashing when receing the request or on startup

Validate that:

Your server is listening on the correct port (e.g. for port http, read the port from PORT_HTTP)
Your server starts immediately when the actor starts (i.e. don't run async code before starting the HTTP server)
You're not using HTTPS for your server (Rivet Guard handles this for you)

If using the actor SDK, this likely an issue with the underlying Rivet library and should be reported on GitHub here.

`404 page not found` when making request to actor

This indicates that there is no actor running for the given address. This often indicates that your actor has crashed and no longer exists.
