Comment Template: error occurs when retrieving comments #69392
Description
Description
Found in this comment: #69378 (comment)
It seems that the Comment Template block is no longer fetching comments in WordPress trunk.
The issue is related to this changeset in core: https://core.trac.wordpress.org/changeset/59899/
If I try reverting the changes in this file, the block will render correctly.
Step-by-step reproduction instructions
- Use the latest WordPress trunk. If you are using wp-env, reset your environment.
- Insert a Comment block into a post. This block contains a Comment Template block as a child.
- A loading icon will be displayed persistently on the block.
- You will see an error in the browser console.
