How to fix "DivergentArrayError: For your own good, using document.save() to update an array which was selected using an $elemMatch projection will not work" in MongoDB
The "DivergentArrayError" in MongoDB/Mongoose occurs when you attempt to save a document after loading it with a partial array projection like $elemMatch. This happens because document.save() would overwrite the entire array with only the projected subset, causing data loss. The error is Mongoose's protective mechanism to prevent this unsafe operation. The solution is to use Model.update() or Model.updateOne() instead of save() when modifying arrays that were queried with projections.
