1Can you add the contents of `package.json` from `functions` folder? – Peter Koltai Sep 29 '21 at 06:22

`{ "dependencies": { "languagedetect": "^2.0.0" } }` @PeterKoltai – Roman Soviak Sep 29 '21 at 07:02

On Firebase Functions init, the `package.json` gets populated with settings like `engines`, dependencies for `firebase-functions` etc., do you have these as well? – Peter Koltai Sep 29 '21 at 07:26

@PeterKoltai I fixed it by using this [answer](https://stackoverflow.com/a/69372091/7856586) – Roman Soviak Sep 29 '21 at 07:27

@PeterKoltai How can I get this info from functions from my Firebase? – Roman Soviak Sep 29 '21 at 07:28

@PeterKoltai functions were written by hand and I don't use it in my flutter web app – Roman Soviak Sep 29 '21 at 07:30

1If you want to use Firebase Functions, then you have to initialize it with `firebase init functions`, which creates `functions` folder with necessary files. – Peter Koltai Sep 29 '21 at 07:37

1If you don't use, then you should not deploy functions. – Peter Koltai Sep 29 '21 at 07:38

(Funny thing here: you have `languagedetect` package, but the error message is not about this, but because it can't detect the programming language of functions.) – Peter Koltai Sep 29 '21 at 07:39

I came across this issue with a custom build process and pointing only to my dist folder.
There are three requirements for a successful build:
- a
firebase.jsonwithfunctions.sourcepointing to a directory containing apackage.json - The
package.jsoncontaining a"main":"path-to-index.js"field. - A node engine specified in either the
package.jsonorfirebase.json
//firebase.json
{
"functions": {
"source": "./some-dir"
}
}
//some-dir/package.json
{
"main": "lib/index.js",
"engines": {
"node": "16"
}
}
