I think conform expects us to use the key from field for everything to work correctly.

See e.g. edmundhung/conform#600 (comment)

Nice find, thanks! So the option here is to ignore them. I'll try to make a demo production version of this. I'd presume React would suppress these errors in production and we'll only have to deal with them in dev environments.

This should be fixed by edmundhung/conform#837, but will need to upgrade to 1.4.0
