Table of Contents: Preventing Editing Rest of Post

[PhilosophyIsMyJam]

Description

I have put the list of contents block in all of the blog posts. However, when I click on the blog post to go back and edit, the editor never loads and I can't access the post. I received a RangeError: Maximum call stack size exceeded on one of the attempts of trying to load the blog page and listed the gutenberg plugin. I uninstalled the gutenberg plugin and only then was I able to access the blog post again. I also removed the list of contents block from the blog post and reactivated gutenberg and I could also then access the blog post editor again. The list of contents block seems to be working fine on the published website itself.

Full error message
RangeError: Maximum call stack size exceeded

Hi, @PhilosophyIsMyJam

Do you mean the Table of Contents block?

A few additional questions:

• What version of the Gutenberg plugin are you using?
• On average, How many heading blocks are in 2000-word blog posts?

[PhilosophyIsMyJam]

Version 17.0.2

Usually 8-15 headings

I tried to reproduce this on v18.7.1 but was unable. I tested up to ~5000 words and 70 headings, with headings maximally nested. I am able to add the Table of Contents block, publish, and return to edit the post with no errors.
