VistasHow to delete a field in a collection with firebase-admin?
I have a collection like this into firebase realtime database:
I need to delete the first element (the one that finishes with Wt6J) from server side using firebase-admin.
I have this simple code:
const deleteNotification = () => {
const key1 = 'FhN6Ntw8gyPLwJYVzcHy0E8Wq5z2';
const key2 = '-MzGhZ2psGLivIfTWt6J';
const notsRef = db.ref(`notifications/${key1}/${key2}`);
notsRef.remove();
};
This doesn't work. What method should I use to delete a specific field? How do you think I can do it?

I would think to use await in a try catch block. Await starts another thread which returns once it has completed. As people said above - your cloud function is likely being killed before the remove actually happens.
const deleteNotification = async () => {
try{
const key1 = 'FhN6Ntw8gyPLwJYVzcHy0E8Wq5z2';
const key2 = '-MzGhZ2psGLivIfTWt6J';
const notsRef = db.ref(`notifications/${key1}/${key2}`);
await notsRef.remove();
} catch( err ) {
console.log( 'failed to remove record.' );
console.log( err );
}
console.log( 'removed record successfully.' );
};
