"on [block] placed/broken" always fail with "Oops, don't know this block"

It seems that any MakeCode project using the "on [block] placed" or "on [block] broken" blocks fail and emit a  "Oops, don't know this block" error, regardless of the block type chosen.

↓

The corresponding Javascript MakeCode is

blocks.onBlockPlaced(GRASS, function () {

    player.say(":)")

})

 

This happens regardless of the block, or even if one uses a convoluted thing like

blocks.onBlockBroken(blocks.blockByName(blocks.nameOfBlock(GRASS)), function () {

    player.say(":O")

})

 

(to maybe avoid some internal inconsistency between these ids.).

 

I'm shocked that such basic functionality is not automatically tested prior to release...

  Hey Angel,

  Sorry to hear you are running into some issues with this as well. Just had a few questions to help us support you further:

  1 - Does it just happen in this world or are you having coding issues in other worlds as well?

  2 - Is it affecting all students or just a few?

  3 - Which block is it not recognizing, is it the grass block same as above?

  4 - Do you have any other screenshots that could be helpful here? (no personal info please)

  Thanks!
