I use mongod of 4.2.0 to start MongoDB server with 'mongod -f test.yml'.

But something went wrong, like:

MacBook-Pro:mongo37017 jackin$ mongod -f test.yml
Unrecognized option: storage.journal.commitIntervalMs
try 'mongod --help' for more information

Use the 4.0.5 version of mongod to start normally.

This looks like a bug in 4.2.0 mongod.

Attachment is my configuration file.

THX.
