the current code is
process.env.FIREBASE_CONFIG = JSON.stringify({
databaseURL: `${process.env.DATABASE_URL}` ||
`https://${process.env.GCLOUD_PROJECT}.firebaseio.com`,
storageBucket: `${process.env.STORAGE_BUCKET_URL}` ||
`${process.env.GCLOUD_PROJECT}.appspot.com`,
projectId: process.env.GCLOUD_PROJECT,
});
so if value of process.env.DATABASE_URL be undifined it will be converted to a string of 'undefined' which will result the databaseUrl or storgaeBucket become a string value of 'undefined'
Fix:
Below code fixes the issues, I didn't have access to create branch and submit PR
process.env.FIREBASE_CONFIG = JSON.stringify({
databaseURL: process.env.DATABASE_URL ||
`https://${process.env.GCLOUD_PROJECT}.firebaseio.com`,
storageBucket: process.env.STORAGE_BUCKET_URL ||
`${process.env.GCLOUD_PROJECT}.appspot.com`,
projectId: process.env.GCLOUD_PROJECT,
});
