SyntaxError: await is only valid in async functions

[tobymac208]

"Step 1" fails with error "SyntaxError: await is only valid in async functions and the top level bodies of modules":

exports.auth = functions.https.onRequest((request, response) => {
  const { url, codeVerifier, state } = twitterClient.generateOAuth2AuthLink(
    callbackURL,
    { scope: ['tweet.read', 'tweet.write', 'users.read', 'offline.access'] }
  );

  // store verifier
  await dbRef.set({ codeVerifier, state });

  response.redirect(url);
});

Please help.

But is supported in Node version later 14

Try adding "async" in front of the function keyword if you're using an older version of node js.

Edit : sorry, you shouldn't add "async" before the function keyword as we are using another arrow function after that.
So, the correct place to add async is before (request, response) => {}

I am facing the same issue. Any solutions yet ?

Faced The Same Problem, add async after "onRequest("

exports.auth = functions.https.onRequest(async (req, res) => {

I'm new to javascript. Would someone mind explaining why only step 1 needs async? Do they others need it to in the arrow functions?

I had to add async to all 3 functions for it to work

I'm having the same issue, I'll try adding async, but if someone knows how to change the project version of Node, that would be super helpful. I'm using N to version manage node, and v12 isn't one of the versions I have installed. When I run node --version I get the correct version. I'm assuming it's somewhere in the Firebase settings that needs to change, but I can't find where to do it.
