BSON JSON is case sensitive

How frequently does the bug occur?

Always

Description

I created a realm object in Swift using 10.54.5. Trying to read in Realm JS using the latest version 12.8.0.
But the get the below error:
BSONTypeError: UUID string representations must be a 32 or 36 character hex string (dashes excluded/included). Format: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" or "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx".

Further analyzing, I figured out the UUID which has CAPITAL LETTERS in the hex string fails on Realm JS. I hope it to be streamlined across languages.

Stacktrace & log output

Can you reproduce the bug?

Always

Reproduction Steps

As mentioned above. Use Swift Realm to create a DB which has UUID field with caps in the hex string. Example: 285C4789-9AAD-7A82-81C9-CB32966B5DA5. Try reading it on Realm JS. You get the error:

BSONTypeError: UUID string representations must be a 32 or 36 character hex string (dashes excluded/included). Format: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" or "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx".

The same can be seen on Realm Studio as well. Attaching the screenshot:

The UUIDs aren't stored as string data in the database, but Binary (bytes), with a specific sub-type to indicate the interpretation. Therefore I'd be very surprised if this has to do with capital vs non-capital letters, when reading out a UUID.

Can you provide the exact code you're using to generate, store and read these UUIDs?
