Unable to update repository Synth

[Bob Willcox]

I am running the drm-next-4.7 and when I ran synth recently on my system
up update the ports and at the end of the run received these errors:

pkg: wrong architecture: freebsd:10:x86:64 instead of FreeBSD:12:amd64
pkg: repository Synth contains packages with wrong ABI: freebsd:10:x86:64
Processing entries: 100%
Unable to update repository Synth
Error updating repositories!
Unfortunately, the system upgrade failed.

Can anyone help me understand what I need to do to fix this?

Thanks,
Bob
