Description
The customer wanted to use BigInt in a document. We explained that the type is not supported, and gave him a workaround, which appears to work.
SF ticket is https://support.mongodb.com/case/00619212
However, customer says that the driver silently fails.
`Not giving an error and not saving the document are serious bugs. You can see this behavior by executing the following code (without the toBSON, only 1 record is saved and retrived; with the .toBSON , 3 records are saved and retrieved; no error is reported in either case)`
MongoDB Nodejs Driver v3.3.3
Nodejs v 10.15.3
