Use Case

As a driver engineer I want to reduce the difference between node and common driver's spec. Currently our findOneAnd* methods return a wrapped type for the findOneAnd* functions.

User Impact

• This will be a breaking change that will make the ok and lastErrorObject properties inaccessible.
• ok's value is implicit by the method not throwing
• lastErrorObject should likely convert to an error as well so there's no need to provide a way to access it.

Dependencies

• NODE-5241

Unknowns

• none

Acceptance Criteria

Implementation Requirements

• Make the findOneAnd functions spec compliant by default: update `includeResultMetadata` to default to false
• make sure findOne() also returns results consistent with the other methods (i.e., null instead of undefined for both flag settings)

Testing Requirements

• modify spec test runner to no longer access the value property
• update the default behavior tests
• update any tangential tests that rely on the default behavior to access the value directly or to use the explicit flag setting

Documentation Requirements

• Document change in the migration guide
• DOCSP ticket to update any documented defaults and examples

Follow Up Requirements

• Heads up to dev tools & mongoose
