Tsed: [QUESTION] v6 with Mongoose fails on Heroku

[royibernthal]

I tried to push to heroku a close-to-clean project with mongoose and got runtime errors right off the bat.

It's the same repo I shared with you before, with minor changes that shouldn't have made a difference as far as this issue is concerned:
https://github.com/royibernthal/tsedrepro

node dist/index.js doesn't throw any errors when testing locally (after building of course).

Here's the error log:

> [email protected] start /app
> node dist/index.js

internal/modules/cjs/loader.js:883
throw err;
^

Error: Cannot find module 'change-case'

Hello @royibernthal
You're not the first to ask me about this issue. I don't know why it occurs because change-case is dependencies of @tsed/schema and this package is a dependencies of your project. Npm should install this dependencies as expected but for an obscure reason the package isn't installed on heroku.

The caveat is to install the change-case as your dependencies on your project until I haven't a proper solution.

I'll try to investigate on it :)

See you
Romain

Hey Romain,

I agree it sounds like a weird issue, though it seems you quickly resolved it. Thanks yet again :)

It's interesting. In the package-lock.json, npm consider the package as devDep:

    "change-case": {
      "version": "4.1.2",
      "resolved": "https://registry.npmjs.org/change-case/-/change-case-4.1.2.tgz",
      "integrity": "sha512-bSxY2ws9OtviILG1EiY5K7NNxkqg/JnRnFxLtKQ96JaviiIxi7djMrSd0ECT9AC+lttClmYwKw53BWpOMblo7A==",
      "dev": true, ////

To reproduce the bug locally run npm ci.

Solved with 6.34.3
