I got an error while using activateBlock
Here's my code
rightClickAt(bot) {
const targetPosition = new Vec3(8,4,8);
const blockAbove = bot.blockAt(targetPosition.offset(0, 1, 0));
bot.activateBlock(blockAbove);
}
This is an error
"C:\Program Files\nodejs\node.exe" ".\xin bot\index.js"
成功加入服务器

The block above does not exist, and you need to check for its existance before trying to call activateBlock
