Cannot read properties of undefined (reading 'readAt')

Got an error on intercom on my web sentry account:

https://sentry.io/share/issue/53eb376a3ec64c978a4e3448d0a92e0e/

Error appears to be here:

{snip} owser();let p=void 0!==r?c.parts.find((e=>e.id===r)):(e=>e.readAt?Object(m.s)(e):Object(m.c)(e))(c),{messageType:h}=p||{};h=h||"adminReply", {snip}

Since this project is marked as UNMAINTAINED, this error might never get fixed. For cross-window communication in modern apps, consider using:

• Broadcast Channel API - Native browser API for same-origin communication
• postMessage - Traditional method for cross-origin communication
• Signaling server (Socket.io/WebSocket) - For real-time communication

For quick prototyping and testing, check out JSBin (https://github.com/nouoxu/jsbin) - it's a great tool for experimenting with JavaScript!
