How can I access a variable in an async method?

Question

Node.js

await sendEmail(req.body.email, this.verificationCode) throws an error that this.verificationCode = undefined, how can I fix this?

class VerificationCodeController{
  constructor(){
    this.verificationCode = generateCode()
  }
     async sendCode(req, res){
     await sendEmail(req.body.email, this.verificationCode)
      return res.json(responseCreator.response(this.verificationCode));
    }
}

Answer 1

Are you initializing variables in the constructor? If so, check what the generateCode() function returns
