createCodeBlockPlugin > Select 2 lines and click on CodeBlock trigger error "Cannot get the next path of a root path [], because it has no next index."

Description

When you select two lines to convert it to a code block, there is an error `Cannot get the next path of a root path [], because it has no next index.``

NB : when you just select one line or a word, instead of creating a new code block with the selected words, it's creating an empty code block under the selection.
