Tellraw command “not reading the t!”

Question

I tried to enter this command:

/tellraw @a Herobrine joined the game

But the error message says ”Unknown command ellraw”

So it seems as if it is not reading the t! /tp is working

/ tellraw @a Herobrine joined the game

is not working

Why is the game not reading the t in the tellraw command?

I am playing on Windows 10 ( bedrock edition)

Answer 1

The reason why the t isn't there is that the problem is "Herobrine" because you didn't use JSON format. If you check the error message you can see that the end was cut off as well:

The correct way is to use JSON which would be like this:

/tellraw @a {"rawtext":[{"text":"Herobrine joined the game"}]}
