Locally building attempt with docker build . -t trivy-db results in COPY failed: no source files were specified

[shoguevara]

I pretty much guess that I'm doing something wrong, but on attempt to build database locally (in a VM with ubuntu22) using
build . -t trivy-db
command, the process goes through all stages seemingly correctly, but in the very end stops with the message:

Step 8/9 : FROM scratch
 ---> 
Step 9/9 : COPY --from=builder /build/assets/trivy*.db.gz .
COPY failed: no source files were specified

As a result there is an image 4.5G in size without any labels in docker image list (I guess it's intermediary uncopressed image with the definitions and vuln bases)
Tried to dig around but quickly realized that's it a bit more than I can chew on right now

Same operation on my mac seemingly concludes without error messages, but the resulting file is less than 1M. Definately not the size it should be.
