firebase函数https.onrequest with async失败eslint

我有FireBase功能

exports.oauth = functions.https.onRequest(async (request, response) => {

对于它,eslint抛出错误如下

  11:69  error  Parsing error: Unexpected token =>

✖ 1 problem (1 error, 0 warnings)

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! functions@ lint: `eslint .`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the functions@ lint script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

这里有什么问题?
