DeprecationWarning: Mongoose: The `strictquery` Option Will Be Switched Back To `false` By Default In Mongoose 7

The error you encountered is a deprecation warning related to the Mongoose package in JavaScript.

In Mongoose version 7 (which is currently in development), the strictQuery option will be reverted back to its default value of false.

strictQuery is an option that controls whether Mongoose should strictly check the query object for any keys that do not correspond to properties in the document schema. When it is false, Mongoose will not throw errors for unrecognized query keys.

To address this warning, you have a few options:

  1. If you don’t want to see the warning, you can explicitly set strictQuery: false in your Mongoose configuration options.
mongoose.set('strictQuery', false);
  1. If you want to keep the stricter query behavior, you can explicitly set strictQuery: true in your Mongoose configuration options. This will make the warning go away since you are already using the default behavior.
mongoose.set('strictQuery', true);

It’s important to note that this deprecation warning is only relevant if you’re currently using Mongoose version 6 or lower, where the strictQuery option defaults to true. If you’re already using Mongoose version 7 (or later), the warning can be ignored since the default behavior will be false.

Therefore, it’s recommended to update your Mongoose version to the latest stable release or follow the Mongoose documentation for any breaking changes related to the strictQuery option.
