This morning, our database flagged a duplicate UUID (v4). I checked, thinking it may have been a double-insert bug or something, but no.

The original UUID was from a record added in 2025 (about a year ago), and today the system inserted a new document with a fresh UUIDv4 and it came up with the exact same one:

b6133fd6-70fe-4fe3-bed6-8ca8fc9386cd

We're using this:\nhttps://www.npmjs.com/package/uuid

I thought this is technically impossible, and it will never happen, and since we're not modifying the UUIDs in any way, I really wonder how that.... is possible!? We're literally only calling:

import { v4 as uuidv4 } from "uuid";

const document_id = uuidv4();

... and then insert into the database, that's it.

Additionally, the database only has about 15.000 records, and now one collision. Statistically... impossible.
