如何为 onCall firebase 函数系统创建异步函数

Question

I'm trying to upload my cloud functions but I have an error during the upload :

  14:63  error  Parsing error: Unexpected token =>

The function :

exports.deleteUser = functions.https.onCall(async (data, ctx) => {
  //my code
}

The error is the arrow...

But this error happen just when I deploy my functions on the cloud but with the emulator nothing appear.

The code provided is correct, you most likely have eslint added and configured to default's which have very strict settings. Setting the Env value to es6 or newer should resolve this issue.

  env: {
    es6: true,
    node: true,
  },
  "parserOptions": {
    "ecmaVersion": 2018
  }
