Did I type something wrong?

The red line points to "bridge:rotate_y_on_place." And this line seems to be the problem.

I'm in the process of adding a block to Minecraft Bedrock Edition. It works. I can assign the block to myself via a command and then place it as desired. Until I want to make it possible to place the block in different rotations or directions.

As soon as I program this, the add-on stops working. I can activate it in the world, but the block is no longer available. It's simply no longer there. What could be causing this?
