During the implementation of Laravel Echo with Ably, an error occurs when channelName = null. Although the server still returns a token, Ably throws the following error:
Auth.requestToken(): token request signing call returned error; err = TypeError: Cannot read property 'split' of undefined
This error occurs because Ably attempts to process the token but encounters an undefined or improperly formatted value. The possible causes include an invalid response format from the server or a token that lacks the required data.
Specifically, when channelName is null, the authentication process may generate a malformed token. If Ably then calls .split() on this token and it is either missing or incorrectly structured, a TypeError is triggered. As a result, the connection to the event channel fails, preventing the client from receiving real-time data.
To diagnose this issue, it is necessary to inspect the server response to ensure the returned token is valid and properly formatted, while also verifying how Ably processes the token during authentication.
import Echo from "@ably/laravel-echo";
import * as Ably from "ably";
import { BaseHttpService } from "@/services/BaseHttpService";
global.Ably = Ably;
export const initializeEcho = async () => {
const echo = new Echo({
broadcaster: "ably",
useTls: true,
requestTokenFn: async (channelName: string, existingToken: string) => {
let postData = { channel_name: channelName };
const res = await new BaseHttpService().https({
method: "POST",
url: "/broadcasting/auth",
authentication_requested: true,
body: postData,
});
return res.token;
},
});
return echo;
};
