SyntaxError: Unexpected Token { on v1.11 after yarn start

[haelbichalex]

Current behavior

When running yarn start I see the following error in pm2 logs for server and it fails to start:

40|server  | /core/scripts/server.ts:1
40|server  | import { serverHooksExecutors } from '@vue-storefront/core/server/hooks'

yarn start should work without errors

@haelbichalex I've just tested that, everything works fine. Could you maybe add some details about that?

This happens for me on our staging environment, here's the yarn pm2 report:

Also, I got it to work with the follwing ecosystem.json

{
  "apps": [
    {
      "name": "server",
      "max_memory_restart": "1G",
      "instances": "4",
      "exec_mode": "cluster",
      "env": {
        "TS_NODE_PROJECT": "tsconfig-build.json",
        "NODE_ENV": "production"
      },
      "script": "./node_modules/.bin/ts-node",
      "args": "-P ./tsconfig-build.json ./core/scripts/server.ts",
      "node_args": "--max_old_space_size=1024",
      "log_date_format": "YYYY-MM-DD HH:mm:ss",
      "ignore_watch": [
        "core/build/config.json",
        "node_modules"
      ]
    }
  ]
}

Also I found something interesting in pm2 logs, but I couldn't find out why it's happening, sind I'm able to run yarn ts-node:

Failed to load Typescript interpreter: Cannot find module 'ts-node/register'

Hi, I have the same problem, today I went crazy during production deployment and after several hours I discovered the problem is base code from release branch v1.11.
When I switch to master, everything works as expected, in our dev branch (based on release/v1.11) pm2 processes do not start at all with the following error:

[2019-11-26 16:08:15] PM2 log: Script C:\Users\libor.pansky\source\repos\vue-storefront\core\scripts\server.ts had too many unstable restarts (16). Stopped. "errored"

(there's probably missing pm2 environment variable pm2_env)

PM2 module error is the same as @haelbichalex 's:

Ok, thanks for reporting we'll try figure it out as soon as possible.

[andrzejewsky]

@cdshotels-liborpansky @haelbichalex are you guys on our community slack? I'd like to ask you few questions, that would be helpful for me.

[haelbichalex]

@andrzejewsky sure 😉 PM'ed you

I had a similar problem with the new API yesterday. Files while building process are transformed to the different compatibility mode (commonjs and stuff like that). I am not sure if the same happens in the PWA. But it might be that.

Sooo... the reason of error could be import from dist to some file which is outside of the dist. For example, in src

Hello, above fix didn't work for me in the same error. I was reading this and I tried to run this command :
"pm2 start /path-to/vuestorefront/vue-storefront/core/scripts/server.ts"
And then this error showed up
[PM2][ERROR] Interpreter /usr/lib/node_modules/pm2/node_modules/.bin/ts-node is NOT AVAILABLE in PATH. (type 'which /usr/lib/node_modules/pm2/node_modules/.bin/ts-node' to double check.)

So I went to /usr/lib/node_modules/pm2/node_modules/.bin/ts-node and I installed typescript from there
And this error went away, but I'm still getting 502 in server
