Cannot "remix-serve" because REMIX_DEV_HTTP_ORIGIN not set

[vrn-dev]

Hi, I have built an app on remix 1.19.3. Once I ran pnpm remix build I got the build folders with no problems. But when i run pnpm start or remix-serve build I get the following error.

> remix-serve build

Remix App Server started at http://localhost:3000 (http://192.168.0.154:3000)

/xxx/node_modules/.pnpm/@[email protected]/node_modules/@remix-run/server-runtime/dist/dev.js:17
  if (!origin) throw Error("Dev server origin not set");
                     ^
Error: Dev server origin not set
    at Object.broadcastDevReady (/xxx/node_modules/.pnpm/@[email protected]/node_modules/@remix-run/server-runtime/dist/dev.js:17:22)

Which basically means that process.env.REMIX_DEV_HTTP_ORIGIN is not set. Can someone let me know what this variable is?

It also seems my build command is keeping my NODE_ENV=development

> remix build

 info  building... (NODE_ENV=development)
 info  built (1.3s)

Can someone please point out where to look to check what has gone wrong.

Had to set env variables correctly as they were not being picked up by remix in production mode.

Seeing the same issue. Can you elaborate on what variables you needed to set

Seeing this same issue as well, setting: REMIX_DEV_ORIGIN to localhost, and this does not work. Should this env var be set automatically somewhere that may not be running on my end properly?

Followed this v1 -> v2 remix guide (I'm on 2.0.1) and was able to resolve my issue: Upgrading to V2. Specifically changing my dev script to running remix dev --manual -c 'node ./server.js' did the trick (make sure you get the build path right).

I was getting this error running it in Docker.

In Remix. Anything but NODE_ENV=production is resolved as development so it will setup a development environment with hmr, reload, etc.
That is why running with --manual solves, it disables all that.

I fixed changing to NODE_ENV=production. remix-serve ./build/index.js
