The code sample for the GetFriendsAsync (Players | Documentation - Roblox Creator Hub) doesn’t run due to a syntax error on line 33:
-- and finally, print!
print("Friends of " .. USERNAME .. ": " table.concat(usernames, ", "))
-- local USERNAME = "Sh:33: Expected ')' (to close '(' at column 10), got 'table'
To fix this, add the missing .. right before table.concat:
-- and finally, print!
print("Friends of " .. USERNAME .. ": " .. table.concat(usernames, ", "))
-- ^^ add this
