Firebase secrets not defined in process.env

Question

I'm writing a Firebase function with Cloud Storage trigger. Like this

const functions = require('firebase-functions')
const doSomethingWithSecrets = require('./doSomethingWithSecrets')

const doSomethingWhenUploaded = functions.runWith({
  secrets: ["MY_SECRET_1", "MY_SECRET_2", "MY_SECRET_3"]
}).storage.object().onFinalize(o => {
  functions.logger.debug([
    process.env.MY_SECRET_1  // undefined
    process.env.MY_SECRET_2  // undefined
    process.env.MY_SECRET_3  // undefined
  ])

  doSomethingWithSecrets(process.env.MY_SECRET_1, process.env.MY_SECRET_2, process.env.MY_SECRET_3)
  // Error: Invalid secret.
})

All three of them returns undefined. I've made sure that they're properly set. They show up both when using firebase functions:secret:accesss MY_SECRET_1 and in Google Cloud Console.

What's wrong?

Additional info

I previously used it with only one secret and it worked. I don't know what happened, I'm using nvm and lost track of which Node version I used when it worked, so it may be a clue.

process.env returns all the env like normal and none of my secrets shows up.

Have you tried debugging only the process.env? Since upon replicating your code on my end, it returned properly. Also, do you have any guides/documentation that you follow, if so, include it in your question. – Malayalam

@Malayalam I added the information you requested. – Seafood

Update your firebase-tools and the issue will resolve itself. I was dealing with this issue all day today and found a git hub issue that fixed the problem in the latest release of 10.9.2.

npm install -g firebase-tools

I encountered the exact same issue. After much suffering I finally got it to work. When you start using secrets in your functions, you need to redeploy all functions and NOT just the individual function.

e.g

firebase deploy --only functions:myFunc

results in my secret values coming through as 'undefined' when accessed from my function using runWith(), however after doing a full functions deploy

firebase deploy --only functions

everything worked.
