under the addons/web/static/src/core/domain_selector/domain_selector_operator_editor.js there is a function 

/** @odoo-module **/

export function getDomainDisplayedOperators(fieldDef) {
    if (!fieldDef) {
        fieldDef = {};
    }
    const { type, is_property } = fieldDef;

    if (is_property) {
        switch (type) {
            case "many2many":
            case "tags":
                return ["in", "not in", "set", "not_set"];
            case "many2one":
            case "selection":
                return ["=", "!=", "set", "not_set"];
        }
    }

    switch (type) {
        case "boolean":
            return ["is", "is_not"];

            return ["=", "!=", "in", "not in", "set", "not_set"];
        case "char":

        case "html":
            return ["=", "!=", "ilike", "not ilike", "in", "not in", "set", "not_set"];
        case "date":

        case "properties":
            return ["set", "not_set"];
        case undefined:
            return ["="];
        default:
            return [
                "=",
                "!=",
                ">",
                ">=",
                "                "                "ilike",
                "not ilike",
                "like",
                "not like",
                "=like",
                "=ilike",
                "child_of",
                "parent_of",
                "in",
                "not in",
                "set",
                "not_set",
            ];
    }
}

and I want to modify/patch this function (note that this function doesn't belong to any class, and it's used in multiple places) 

I tried to replace it and I got an error

this is my manifest 

'assets': {
    'web.assets_frontend': [
        ('replace', 'web/static/src/core/domain_selector/domain_selector_operator_editor.js', 'my_module/static/src/components/domain_selector/domain_selector_operator_editor.js'),
    ],
    'web._assets_core': [
        ('replace', 'web/static/src/core/domain_selector/domain_selector_operator_editor.js', 'my_module/static/src/components/domain_selector/domain_selector_operator_editor.js')
    ],
},

The error

any help!
