Accessing data within cloud function Firebase

I'm trying to access data from firebase cloud function.

I have group of users (like a group chat) and each group has key.

I try to access the group within a cloud function :

admin.database().ref('/GroupUsers/${groupKey}').once('value');

and get the following error:

          Error: Firebase.child failed: First argument was an invalid path: "/GroupUsers/${groupKey}". Paths must be non-empty strings and can't contain ".", "#", "$", "[", or "]"
at Error (native)

If you want to insert a variable inside a string in JavaScript, use backticks to delimit the string (you're using single quotes).

admin.database().ref(`/GroupUsers/${groupKey}`).once('value');
