I am trying to implement firebase with golang and have been successful so far. My code works fine when I run it locally and I can see the data in the firebase database. But when I deploy the code on GKE(GCP), it doesn't work and throws the following error. I am a beginner in goalng . Please help me fix this. What am I doing wrong? Please comment if you need more information

Never ignore any error. Print error of this line. This might be the root cause.
app, err := firebase.NewApp(context.Background(), conf, opt)
If firebase.NewApp() fail, it will return error and app will be nil. As you are trying to access app.Database() on next line, you will get that panic since app is nil.
