Firebase 无效 api 控制台中的密钥错误（错误（auth/invalid-api-key））

Question

I'm keeping the key value. The boot is giving me this error.

My code works fine if I don't use env variables, but I get this error when I use env variables.

.env.local code:

API_KEY=AIzaSyBPDUsNpEspYB-b_q8YUemjg8mp26BJCn0
AUTH_DOMAIN=phonesy-ad56a.firebaseapp.com
PROJECT_ID=phonesy-ad56a
STORAGE_BUCKET=phonesy-ad56a.appspot.com
MESSAGIBG_SENDER_ID=304429202901
APP_ID=1:304429202901:web:9b3c2fab35b3c4f36c115c

firebase init code:

apiKey: process.env.API_KEY,
authDomain: process.env.AUTH_DOMAIN,
projectId: process.env.PROJECT_ID,
storageBucket: process.env.STORAGE_BUCKET,
messagingSenderId: process.env.MESSAGIBG_SENDER_ID,
appId: process.env.APP_ID,

Firstly, do not expose your keys. Edit: Firebase configuration values are not sensitive.

The problem is, you are using ".env.local". That is for local environment variables.

Rename your file to ".env", restart your server. Or create new file named ".env"
