Since you’re using loader-nextjs you shouldn’t import things from @plasmicapp/host. You should also be registering your components using the loader instance like so: PLASMIC.registerComponent(...)
Looking at the plasmic-host file, it seems that the import path for WorkSlider is wrong. Try removing the .jsx at the end. Also, I would recommend moving the registration to plasmic-init.
Ah thank you I don’t know how I didn’t realize the typo. I renamed the file and moved the registration to plasmic-init, and it is working fine now. Thank you very much.
