TypeError: moduleDecl.body.body.forEach is not a function

See original GitHub issue

Hi! I have a strange error

TypeError: moduleDecl.body.body.forEach is not a function
Occurred while linting ~/services/admin-website/src/views/Products/Products/AddProductDialog/PhotoInput/index.tsx:1

the first line is

import React, { Fragment, FC, useState, ReactElement } from 'react'

so this is something else

I personally think the problem comes from another. file

import * as firebase from 'firebase/app'
import 'firebase/auth'
import 'firebase/firestore'
import 'firebase/storage'

import config from './production.config'


if (!firebase.apps.length) {
  firebase.initializeApp({
    ...config,
    timestampsInSnapshots: true,
  })
}

export default firebase
