Description
[REQUIRED] Step 2: Describe your environment
- Operating System version: macOS 14.5 (23F79)
- Firebase SDK version: 12.2.0
- Firebase Product: database
- Node.js version: v20.13.0
- NPM version: v10.5.2
[REQUIRED] Step 3: Describe the problem
If a transaction is pending for a node, it doesn't show up when reading data for the parent node with .once("value", ...)
. I'm not sure if this is a bug or intended behavior.
Steps to reproduce:
For these examples, our database looks like this:
{
"example_list": [
"a",
"b",
"c"
]
}
This code works as expected:
let ref = admin.database().ref("example_list");
ref.once('value', (snap) => {
console.log(snap.val())
});
Logs: [ 'a', 'b', 'c' ]
This code does NOT work as expected:
admin.database().ref("example_list/1").transaction((currentData) => {
return currentData;
});
let ref = admin.database().ref("example_list");
ref.once('value', (snap) => {
console.log(snap.val())
});
Logs: [ 'a', <1 empty item>, 'c' ]
Adding a transaction first, which seems like a no-op, actually causes the read to return a different result.
