@micmc I worked through this and got everything working in the past. I had to install the directus-cli on my local machine and use something like Visual Studio Code or similar program to connect to my Directus instance hosted inside Cloudron, to run the AgencyOS importer.
Separate from that, I forked the "AgencyOS" code base to a private Github repo and published using Vercel for the frontend.
Based on my experience, because anything outside of /app/data/ on Cloudron is read only, I had to break apart the AgencyOS frontend and then just connect back to Directus.
I'd be aware, AgencyOS is still under active development and it was created as more of a proof of concept, so in my experience you're bound have quite a few issues. But I got it working in the past, but take lots and lots of backups for both the frontend and your directus instance.
