Question

I am getting the error Parsing error: Unexpected token => when I try to deploy my Vue JS application to firebase. The application runs fine on my local machine but I am not able to deploy to firebase.
Here is the full error

I have added ecmaVersion: 8 to parserOptions. I have changed it to 6, I have also changed it to 2017 as suggested by some other answers.
Here is my .eslintrc.js file
module.exports = {
root: true,
env: {
node: true
},
extends: ["plugin:vue/essential", "#vue/prettier"],
rules: {
'no-console': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
'no-debugger': process.env.NODE_ENV === 'production' ? 'warn' : 'off'
},
parserOptions: {
parser: 'babel-eslint',
ecmaVersion: 2017
},
'extends': [
'plugin:vue/essential',
'#vue/prettier',
'#vue/standard'
]
};
Here is my package.json file

}
None of the the other resources I have read points out the problem to be from their code. But I am just adding functions/index.js here incase the problem is from the that file.
const functions = require("firebase-functions");
const admin = require("firebase-admin");
admin.initializeApp();
const db = admin.firestore();
exports.addUserRole = functions.auth.user().onCreate(async (authUser) => {
if (authUser.email) {
const customClaims = {
admin: true,
};
try {
let _ = await admin.auth().setCustomUserClaims(authUser.uid, customClaims);
return db.collection("roles").doc(authUser.uid).set({
email: authUser.email,
role: customClaims,
});
} catch (error) {
console.log(error);
}
}
});
exports.setUserRole = functions.https.onCall(async (data, context) => {
if (!context.auth.token.admin) return
try {
let _ = await admin.auth().setCustomUserClaims(data.uid, data.role)
return db.collection("roles").doc(data.uid).update({
role: data.role
})
} catch (error) {
console.log(error)
}
});
As requested in the comments, I have added my firebase.json
{
"firestore": {
"rules": "firestore.rules",
"indexes": "firestore.indexes.json"
},
"functions": {
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint"
],
"source": "functions"
},
"storage": {
"rules": "storage.rules"
},
"hosting": {
"public": "dist",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [
{
"source": "**",
"destination": "/index.html"
}
]
}
}
