A villager has nothing to trade but I want to level him up to get a valuable asset. I can't level it up because he has nothing to trade what to do?
Then he has no profession. He says you have to set up a composter, for example. Then he becomes a farmer. And then you can also trade with him.
He is a cartographer. He is sold out.
Then you have to give it time and he needs access to his cartographer table or whatever that thing is called.
As long as a villager can work his block, he will reset the offer up to twice a day and then you can trade with him again
The villager resets his offer twice a day. Just wait.
