bow cannot enchant infinity

Bow or crossbow?

the bow ok .

I seem the be able to get infinity. How are you enchanting it?

I press T button, and "/ enchant @a infinity" ,

and then

no mending , just have unbreaking and flame .

Are you on a server?

no , just singleplayer

Cannot reproduce. See

.

Works ok for me on 35a as well. I get that exact same error message if the bow already has mending on it
