Error: component implementation struct cmd.demoImpl has field kod.Ref[github.com/leopku/emeraldpanel/pkg/infra/db.DBComponent], but component db.DBComponent was not registered; maybe you forgot to run 'kod generate'

Any advice?

[sysulq]

Please check if pkg/infra/db/kod_gen.go generated?

Maybe you could also try run kod generate -s ./... instead.

same issue after running kod generate -s ./....

kod.Ref only supports interface, instead of struct 😀

Change db.DBComponent to db.Component would fix it.
