Within my Firestore database, there is a collection named events consisting of documents with attributes such as begin, end, and title. The function in question is triggered when any changes occur within a document.
The begin and end fields are both categorized as type timestamp. My objective is for the function to return false if either begin or end has been modified.
In the cloud function script, I have implemented checks to compare the data before and after changes. Despite this, it returns true, even if only the title field has been altered.
const before = change.before.data()
const after = change.after.data()
//Although begin and end remain unchanged, true is unexpectedly returned
if (before?.begin == after?.begin && before?.end == after?.end) {
return false
}
return true
Strangely, when comparing milliseconds instead, the comparison works correctly:
const before = change.before.data()
const after = change.after.data()
//Even when begin and end stay the same, false is appropriately returned
if (before?.begin.toMillis() == after?.begin.toMillis() && before?.end.toMillis() == after?.end.toMillis()) {
return false
}
Why is this happening? Shouldn't it be possible to compare the Timestamp objects directly rather than relying on a member function?
