Error: Can't use $diacriticSensitive with String.

[bruno2kd]

I'm sorry, I am new to this and I am not sure this is the right place to post.

I am trying to do a diacritic insensitive search:

on the client:

const q = {
                query: {
                    name: {
                        $search: "frénch",
                        $diacriticSensitive: false,
                    },
                },
            };

            const res = await api.products.find(q);

Products hooks:

module.exports = {
    before: {
        all: [],
        find: [
            search({ fields: ["name"] }),
        ],
        get: [],

The error I get:

Error: Can't use $diacriticSensitive with String.

Mongodb: 3.6v
feathers-mongodb-fuzzy-search: 1.1.1v

when I do without the line $diacriticSensitive: false it works right but it is diacritic sensitive.
Also, Mongodb docs says that it defaults to diacritic insensitive and it is defaulting for diacritic sensitive for me.

Any clue on what is going wrong?
