[andysay]

const { NotFound, GeneralError, BadRequest } = require("@feathersjs/errors");
module.exports = (options = {}) => {
    return async (context) => {
        const { app, data } = context;

        const result = app.service("users").find({
            query: {
                //both uniq
                $select: [data.email, data.username],
            },
        });

        const { total } = await result;

        if (total > 0) {
            throw new BadRequest("Invalid Parameters", {
                errors: {
                    //  how get whats really conflict in db?
                   ????  email? username? or both ... i want return to front for exactly status
                },
            });

        }
        return context;
    };
};

I don't think the queries you are making will do what you expect. If you want to differentiate the error message between if email and username already exists, this should work:

const { NotFound, GeneralError, BadRequest } = require("@feathersjs/errors");

module.exports = (options = {}) => {
    return async (context) => {
        const { app, data } = context;

        const { total: emailTotal } = app.service("users").find({
            query: {
                email: data.email,
                $limit: 0
            },
        });
        const { total: usernameTotal } = app.service("users").find({
            query: {
                username: data.username,
                $limit: 0
            },
        });

        if (emailTotal > 0) {
            throw new BadRequest(`Email already exists`)
        }

        if (usernameTotal > 0) {
            throw new BadRequest(`Username already exists`)
        }
    };
};
