Trying to retrieve value from environment file getting undefined in react js

Question

Hi all i have set the variable in environment file like as below

REACT_APP_RECIPIENT_MAIL="[email protected],[email protected],[email protected]"

and then i am retrieving those like as below

  let toArr;
  if (isDevelopmentMode()) {
    const mailList = process.env.REACT_APP_RECIPIENT_MAIL;
    console.log(mailList);
    toArr = mailList.split(',');
  } else {
    toArr = Array.isArray(to) ? to : [to];
  }
  const toAddrs = toArr.map(toAddr => ({
    emailAddress: {
      address: toAddr
    }
  }));

getting undefined at this line console.log(mailList); for mailList and i am not sure where i am doing wrong with the above code, Could any one please suggest any ideas on this?

Many thanks in advance.

Did you stop the server and run npm start again after adding the env var? — domenikk

For the newly added env variables to be available, you need to stop React server and start it again with npm start.
