Grafana Minified React Error #321

[mfb1909]

I was previously using this plugin and had absolutely no problems with it. However since updating my Backstage backend to match the new backend version, I have now encountered this error which has confused me greatly as it's not even in the backend. I've been back through the instructions for adding it to my app, and everything looks the same as before and I can't see any differences with the example and what I have (apart from the DNS etc). I have been through my react and react-dom versions, and they match everywhere.

This is the full error message:
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.

I get this error when I try to run it locally with the example data with the grafana plugin
