Quick question, is bubble creating a UUID as the object ID in the database? I know there are plugins and javascript to create UUIDs; however, I don’t want to go through the effort if it is already built into the core solution. 
I don’t think it does.
Looking at the Bubble Manual, a unique id is a 32-character alphanumeric string of this format:
1651238619517x600101118159717500
Comparing it to a UUID example on Wikipedia it doesn’t seem to follow the same pattern:
In its canonical textual representation, the 16 octets of a UUID are represented as 32 hexadecimal
(base-16) digits, displayed in five groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters (32 hexadecimal characters and 4 hyphens). For example:
123e4567-e89b-12d3-a456-426614174000
