Error in the tutorial: Build your first block

[audunmb]

Description

The tutorial on how to build your first block doesn't work.
On https://developer.wordpress.org/block-editor/getting-started/tutorial/#updating-block-json
it says that you should edit the /src/block.json file and then you're able to see the changes in the active plugin. As the active plugin uses /build/block.json, this won't work.

Step-by-step reproduction instructions

1. Follow instructions
2. Don't see the changes
