n [Error]: Calling faker.helpers.arrayElement() without arguments is no longer supported.

I meet a error with locale: en_US, the code is follow:

    let faker = new Faker({ locale: en_US });
    let email = faker.internet.email();

the call stack is follow:

  <rejected> n [Error]: Calling `faker.helpers.arrayElement()` without arguments is no longer supported.
      at A.arrayElement (D:\project\bill\src\facker-account\node_modules\@faker-js\faker\dist\cjs\modules\helpers\index.js:1:5755)
      at l (D:\project\bill\src\facker-account\node_modules\@faker-js\faker\dist\cjs\modules\person\index.js:1:743)
      at o.firstName (D:\project\bill\src\facker-account\node_modules\@faker-js\faker\dist\cjs\modules\person\index.js:1:1047)
      at E.email (D:\project\bill\src\facker-account\node_modules\@faker-js\faker\dist\cjs\modules\internet\index.js:1:1372)
      at main (D:\project\bill\src\facker-account\main.js:18:32)

but it works well with locale: zh_CN:

    let faker = new Faker({ locale: zh_CN });
    let email = faker.internet.email();

and "version": "8.0.2"

you generally should use the prebuilt faker instances to access locales, for example:

const {fakerEN_US, fakerZH_CN} = require("@faker-js/faker")
fakerEN_US.internet.email()
fakerZH_CN.internet.email()

This ensures that fallback languages are loaded correctly.

Thank you, I tried it works well.

This isnt the error message I would expect.
IMO it should report missing data instead of not providing data to the arrayElements method.

[matthewmayer]

Minimal reproduction for this, showing that faker.person.firstName doesn't use the same error as other missing data.

const {en_US, Faker} = require("@faker-js/faker")
const faker = new Faker({ locale: en_US }) //not recommended
faker.person.firstName() //Calling `faker.helpers.arrayElement()` without arguments is no longer supported.
faker.animal.dog() // The locale data for 'animal.dog' are missing in this locale.
