Invalid hook call when using in Gutenberg

[Rob Ruiz]

Trying to use these in a Gutenberg block (new WordPress editor - which is React essentially). Followed instructions on Github.
Getting:
react-dom.min.js?ver=17.0.1:9 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.

import { Horse } from "phosphor-react"; import { useBlockProps } from '@wordpress/block-editor'; export default function Edit() { return ( <div { ...useBlockProps() }> { __( 'Phosphor Icons – hello from the editor!', 'phosphor-icons' ) } <Horse /> </div> ); }
Error only occurs once I add Horse component
Any ideas here?

For additional context, this only happens when I try to use the component in the save method, but not in the edit method.

Sorry @robruiz, I'm not familiar with Gutenberg, but from the error, your problem is likely to be:

1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.

I would look into pinning your react and react-dom versions in your lockfile to make sure only one version is installed and used.
