Attachment object empty

I’ve been working on a Frontity test based on a local hosted Wordpress with Docker, and React with node version +16. Everything is ok listing and managing info from my Wordpress installation, but when I tried to access to “Attachment” object, everything is empty. No matter what component I’m currently rendering.

I’ve created some ACFs to CPT, one of them to get photos from media library. I can see the ACF image ID when I go to console and type frontity.state.source.projects.acf, but my “Attachment” object stills empty.

I guess everything is fetching fine because I can see all the info but attachment.

Can I get helped please?

Thank you so much in advance!!
