I'm getting the same error under wp-env for all existing and new pages. This appears to be a problem in https://c0.wp.com/c/6.1.1/wp-includes/js/dist/blocks.min.js line 10.

The same here! But I don't have installed Gutenberg plugin. When I install Gutenberg this error disappear. 😑

I am also getting these block validation errors for the 'core/group' block on multiple sites with all plugins disabled, not using the Gutenberg plugin. I'm pretty sure this started within the last 24 hours.

This has been driving me crazy! I'm developing a custom block and I thought I had done something really serious. I created a new, clean site and tested in Chrome & Edge on Windows, and on Safari on Mac. I got the same errors in the console. I also believe it started in the last 24 hours, but I can't figure out what could have changed.
WordPress 6.2-beta5 does not have the error.

I have identified the cause of the problem. I was able to reproduce this issue with a new WordPress 6.1.1 installation.

The problem is that some block patterns retrieved from the remote block pattern directory do not match the block support supported by WordPress 6.1.X.

• https://wordpress.org/patterns/pattern/footer-with-background-color-and-three-columns/
• https://wordpress.org/patterns/pattern/centered-footer/
• https://wordpress.org/patterns/pattern/centered-footer-with-social-links/

As you can see in the error message, those patterns contain group blocks with the min-height style applied. min-height block support will be supported starting with WordPress 6.2, as described in this post.

Therefore, if you add the following code, the error message should not appear.

add_filter( 'should_load_remote_block_patterns', '__return_false' );

However, as noted in this comment, patterns tagged with numbers above the current WordPress version should not be included in the response.

If you know anything about this issue, please let us know 🙏

My quick fix was to remove "dimensions":{"minHeight":"40vh"}} and style="min-height:40vh" from the wp_options table. The options_name is _site_transient_wp_remote_block_patterns_##########.

Since this issue does not appear to be related specifically to 6.2, I am removing it from the project board. But please let me know if I am interpreting the issue.

[ryelle]

Those three patterns were set as "6.1+", so they would load in 6.1. Since it sounds like they should be 6.2+, I've updated the meta on each. They should not be loaded on 6.1.x sites anymore.

Thank you for your response! I have confirmed that the console error no longer appears in WordPress 6.1.1.
