Node.js version

MongoDB server version

Description

mongoose_test.zip

This test case demonstrates inserting a single document with a complex schema. it is actually simplified from out actual schema in use, and I've replace several subdocuments with Mixed. But I expect it is very likely due to the potential recursive nature of the schema.

Works as expected in version 8.2.2, 8.3.0 and 8.4.0. Hangs in 8.4.1 - 8.6.3

Steps to Reproduce

build and run attached app.

Expected Behavior

inserts the document.

Note, when simplifying the schema and replacing other portions with .Mixed, it does not hang, leading me to believe this is not a mongo driver bug.
