I am working with Odoo direct print report in Odoo18 but getting this error while trying to print a report:
TypeError: env.services.rpc is not a function.

Could anybody help what's the solution?
Here is my Javascript code where the error occurs.

/** @odoo-module **/

 *
 * @private
 * @param {ReportAction} action
 * @param {ReportType} type
 * @returns {string}
 */
function _getReportUrl(action, type) {
    let url = `/report/${type}/${action.report_name}`;
    const actionContext = action.context || {};
    if (action.data && JSON.stringify(action.data) !== "{}") {
        // build a query string with `action.data` (it's the place where reports
        // using a wizard to customize the output traditionally put their options)
        const options = encodeURIComponent(JSON.stringify(action.data));
        const context = encodeURIComponent(JSON.stringify(actionContext));
        url += `?options=${options}&context=${context}`;
    } else {
        if (actionContext.active_ids) {
            url += `/${actionContext.active_ids.join(",")}`;
        }
        if (type === "html") {
            const context = encodeURIComponent(JSON.stringify(env.services.user.context));
            url += `?context=${context}`;
        }
    }
    return url;
}
