The error message indicates a TypeError at line 91 of the Message.js file.

/workspaces/whatsapp-ai-bot/node_modules/whatsapp-web.js/src/structures/Message.js:91 this.deviceType = data.id.id.length > 21 ? 'android' : data.id.id.substring(0, 2) == '3A' ? 'ios' : 'web'; ^

TypeError: data.id.id.substring is not a function at Message._patch (/workspaces/whatsapp-ai-bot/node_modules/whatsapp-web.js/src/structures/Message.js:91:75) at new Message (/workspaces/whatsapp-ai-bot/node_modules/whatsapp-web.js/src/structures/Message.js:18:24) at Client.sendMessage (/workspaces/whatsapp-ai-bot/node_modules/whatsapp-web.js/src/Client.js:699:16) at processTicksAndRejections (node:internal/process/task_queues:95:5)

The error message suggests that there is a TypeError in the Message.js file of the whatsapp-web.js module. Specifically, the error occurs on line 91 of the Message.js file.

The error message states that data.id.id.substring is not a function, which means that the substring method is being called on an object that doesn't have that method.

Possible Solutions from whatsapp-web.js issue.

Make this:

Open this file: \node_modules\whatsapp-web.js\src\structures\Message.js

• Go to line 91 and change this:

  this.deviceType = data.id.id.length > 21 ? 'android' : data.id.id.substring(0, 2) == '3A' ? 'ios' : 'web';

• for this:

  this.deviceType = typeof data.id.id === 'string' && data.id.id.length > 21 ? 'android' : typeof data.id.id === 'string' && data.id.id.substring(0, 2) === '3A' ? 'ios' : 'web';

WhatsApp Web updated something that made that line stop working, but using this code it worked for me again.
