getAccountsSchema is returning void

[yannick-beot-sp]

getAccountsSchema is defined as follow:

        /**
         * This API downloads the CSV schema that defines the account attributes on a source. >**NOTE: This API is designated only for Delimited File sources.**
         * @summary Downloads source accounts schema template
         * @param {string} id The Source id
         * @param {*} [axiosOptions] Override http request option.
         * @throws {RequiredError}
         */
        async getAccountsSchema(id: string, axiosOptions?: AxiosRequestConfig): Promise<(axios?: AxiosInstance, basePath?: string) => AxiosPromise<void>> {
            const localVarAxiosArgs = await localVarAxiosParamCreator.getAccountsSchema(id, axiosOptions);
            return createRequestFunction(localVarAxiosArgs, globalAxios, BASE_PATH, configuration);
        },

Even though it should "download" a CSV schema, the method is returning "void".
