flutter: [ERROR]: CreateAuthChallenge failed with error SyntaxError: await is only valid in async function

Question

Getting the captioned error message onTap signUpButton() within AuthenticatorForm(). Seems like a very straightforward error message, but can't seem to identify what's wrong.

Here is my createAuthChallenge.js
```
const digitGenerator = require('crypto-secure-random-digit');

function sendSMS(phone, code) {
  const params = {
    Message: code,
    PhoneNumber: phone,
  };
  return new AWS.SNS({apiVersion: '2010-03-31'}).publish(params).promise();
}

async function createAuthChallenge(event) {
  if (event.request.challengeName === 'CUSTOM_CHALLENGE') {
    const randomDigits = digitGenerator.randomDigits(6).join('');
    const challengeCode = String(randomDigits).join('');
    await sendSMS(event.request.userAttributes.phone_number, challengeCode);
  
    event.response.privateChallengeParameters = {};
    event.response.privateChallengeParameters.answer = challengeCode;
  }
}

exports.handler = async (event) => {
  createAuthChallenge(event);
};
```

And my package.json for the same
```
{
  "name": "XYZ",
  "version": "2.0.0",
  "description": "Lambda function generated by Amplify",
  "main": "index.js",
  "license": "Apache-2.0",
  "devDependencies": {
    "@types/aws-lambda": "^8.10.92"
  },
  "dependencies": {
    "crypto-secure-random-digit": "^1.0.9"
  }
}

```

I can't seem to find the right solution for this, can anyone help please?

Accepted Answer

Not entirely sure what the root cause of the error messages above were, but there is nothing wrong with the codes above.
Redid everything from amplify delete > amplify init > amplify add auth > add lambdas to local > amplify push
And now everything works, most likely some odd mistake that I made without realizing
