Wp-calypso: Posts Carousel Block: Clicking on "Feed Settings" will break block if the Gutenberg plugin is active

[mrfoxtalbot]

Steps to reproduce the issue

1. Create a new post while having the Gutenberg plugin active (8.1.0)
2. Insert a new Posts Carousel Block
3. Click on "Feed Settings"
4. The block will break.

What I expected

The block should not break.

What happened instead

The block breaks :)

Screenshots

This can be seen here https://mrfoxat04.wpcomstaging.com/2020/05/21/post-carousel-block/

WordPress 5.4.1 running Twenty Twenty theme.
This will not happen if the Gutenberg (8.1.0) is disabled.

Transferring this to the Calypso repository where the block is being developed, as part of the Full Site Editing plugin.

I have just noticed that the plugin is now broken on simple sites too :/

@laurelfulford do you think this should be transferred to the Newspack Blocks repo?

[laurelfulford]

Hi @davipontesblog! This doesn't look like the same block as in the Newspack Blocks repo -- despite the confusing name overlap! Inspecting the example site above, the block looks like it's part of Co-Blocks collection:

The similar block in Newspack doesn't have the "Feed" option.

Great, thanks @laurelfulford! I will move this to CoBlocks then a bit later today.

Thanks @davipontesblog!

@mrfoxtalbot this is a CoBlocks block that is not available on simple sites, only on atomic. Would this be perhaps a site that was once atomic and now simple?

[davipontesblog]

I can reproduce this with an atomic site running Gutenberg 8.2.1, our most recent version, so I've reported it here now: https://github.com/godaddy-wordpress/coblocks/issues/1530

I am closing this issue in favor of tracking it on the CoBlocks repo.

I looked up the original ticket and it looks like the offending block was not the co-blocks carousel, the the other one, my bad https://wordpress.com/support/wordpress-editor/blocks/posts-carousel-block/

That being said the block IS Broken on the site being mention in zen-3008719:

I was unable to reproduce this error on other simple sites.

I will open a new issue, please ignore the reference to the block not working on simple sites, as it is a different block.
