Hi Intercom team,
We’re experiencing a React crash that appears to originate inside the Intercom Messenger widget. The error is:
Error: Minified React error #185
Stack trace points into this script:
at Messenger.componentDidUpdate (https://js.intercomcdn.com/app-modern.4b8f9f21.js)
at https://js.intercomcdn.com/vendor-modern.50137b6e.js
Could you confirm if this is a known issue?
Thanks, Markus

Hi Markus,
That specific error (React error #185) usually happens when React detects something unexpected in the way components update. Since your stack trace points directly inside Intercom’s Messenger script, it’s not coming from your own code but from the widget itself.
A couple of quick things you can try while waiting for Intercom support:
Make sure you’re on the latest version of the Messenger snippet.
Clear cache and do a hard reload, just to confirm it’s not serving an outdated script.
Check if this happens across browsers or only in a specific environment.
If it consistently breaks, it’s most likely on Intercom’s side. I’d recommend raising a ticket with their support team (with your logs and environment details) so they can confirm if it’s a known issue or provide a patch.
We had the same issue. I think it’s gone now, but the fact that the widget is able to flood the whole page with a big wall of error text is very concerning
