cant summon item

can i just say that the bug tracker service is superb! the second i create an issue the status is open!

You must specify what item you want to summon. For example:

/summon minecraft:item ~ ~ ~ {Item:{id:"minecraft:stone",Count:1b}}

i was but i didnt included count

if you are wondering why you are getting many reports from me is i am working on a project.
what replaced r?

@@unknown Please keep in mind this is a bug tracker, not a help desk. If you need general help with commands, you should be using a different site (such as the MinecraftCommands subreddit).
