Basic template, added kysely, throws trying to find source map

[andreujuanc]

Hi,
I'm testing out remix, and so I created the basic project template, and proceeded to add a loader that gets data from a local postgres.
It all works in dev. But then when I run it in a container after npm run build and npm run start it throw this:

GET / 500 148 - 37.198 ms
Error: ENOENT: no such file or directory, open '/app/node_modules/kysely/dist/esm/query-builder/select-query-builder.js.map'

loader

There is no select-query-builder.js.map at all in kysely's node_module files.

I would appreciate any hits to get it run in "prod".

Thanks

I am having similar issue, but with the Zod library so wanted to share that thread with you so you can follow as well in case it helps.

Latest snippet from discord thread:

I did just try adding the library to the serverDependenciesToBundle option in the remix.config.js file, and it seems to be working now. Not sure if that is the correct way to fix, so would love some feedback from a Remix expert, but wanted to share that solution.

// remix.config.js file
/** @type {import('@remix-run/dev').AppConfig} */
module.exports = {
  serverDependenciesToBundle: ["zod"],
  // ...
};

I just "exited" remix serve" and moved to express" instead, and it worked.
Try it.
