Problem
Transaction.get(ref) followed by transaction.set(ref, {...}) is causing the transaction to fail with error 'Document already exists' if the document was created by another app between the get and set.
Cause
'already-exists' is considered to be a permanent error for transactions, therefore will not be retried.
