Problem Statement/Rationale

We are using spring boot to connect to Mongo DB and save the documents there. Everything seems to be configured correctly. Out of several million documents and daily saves we have spotted 2 weird cases with dates being malformed. See the ``birthday`` field in the attached screenshot. In other instance we had a date that was of "0000.01.01". I am seeing those errors in Compass but our internal tools are failing whenever such malformed date happens. Could you advise me where could be the problem? It happened only twice and we have around few thousands documents saved. We control what is being saved and all dates are converted in Java and MongoDB drivers are used.

Please be sure to attach relevant logs with any sensitive data redacted.
