Hi, using mongodb@3.6.4 on node@14.15.0 I get the following error that comes from write_concerns.js:
Top-level use of w, wtimeout, j, and fsync is deprecated. Use writeConcern instead.
Any idea why I’m getting this warning and how to fix it?
What would be the recommended version of mongodb to downgrade and try to see if such warn dissapears?

this works for me:
WriteConcern:{w:"majority",wtimeout:2500}
