React error coming from Shopify (Minified React error #321)

[Kris_Doyle]

Just started seeing this pop up in the console but I don't use React for anything so this is definitely coming from the Shopify side:

blur.js:42 Uncaught (in promise) Error: Minified React error #321; visit https://reactjs.org/docs/error-decoder.html?invariant=321 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.
at it (blur.js:42:3933)
at s.useContext (blur.js:42:5675)
at cr (blur.js:57:31858)
at blur.js:61:494
at blur.js:126:5191
at Generator.next (<anonymous>)
at I (blur.js:126:4967)

It's not causing any issues that I can see, just wanted to mention it 🙂

I get this exact error stack every time I instantiate a create-react-app, and it appears in the console in my express/react app currently deployed on AWS (www.thehoopscoop.org), was never there before.

The reason for this error is the Google Chrome extension (see screenshot).
After research i found that the extension "Loom – Screen Recorder & Screen Capture" caused this error message.
You can just ignore this error or remove Loom from your Chrome extensions.

This solved it for me.  Thank you!

Odd that Loom is causing this, but it does indeed solve the issue (albeit at the loss of Loom).

Thanks!
