Describe the bug

Error when calling bulk_write function.

BE SPECIFIC:

• What is the expected behavior and what is actually happening?
  bulk_write fn is supposed to work fine like other DB operations (insert_one, update_one, delete_one...). Also, defined namespace as well.
• Do you have any particular output that demonstrates this problem?

Error: Kind: Command failed: Error code 8000 (AtlasError): missing nsInfo, labels: {}

• Do you have any ideas on why this may be happening that could give us a
  clue in the right direction?
  I searched in the internet, may be due to the cluster being shared which I don't believe.
• Did this issue arise out of nowhere, or after an update (of the driver,
  server, and/or Rust)?
  I am using bulk_write for the 1st time in any of the rust crate version. So, not sure about its output in older version.
• Are there multiple ways of triggering this bug (perhaps more than one
  function produce a crash)?
• If you know how to reproduce this bug, please include a code snippet here:

FIX:
Upgraded my shared cluster (FREE tier) to a dedicated cluster (Paid tier).
