Minecraft saying "minecolonies requires domum_ornamentum 1.20.1-1.0.184-BETA or above" I think it just typo in name version but not sure(it must be domum_ornamentum-1.20.1-1.0.279-snapshot-universal I think)

That error message is automatically generated from the actual version number it checks against. It cannot have a typo, and in fact I see a "1" there in the error message you posted
(The -BETA / -snapshot-universal part doesn't matter for version matching)

I don't know how to answer on this, I can't understand what do you mean

I'm getting the same issue.
The version being pushed via curseforge is 0.0.279
It probably should read 1.0.279

Same issue here. The file name is domum_ornamentum-1.20.1-0.0.279-snapshot-universal.jar
I think it should be domum_ornamentum-1.20.1-1.0.279-snapshot-universal.jar
