@youknowriad does this need to be part of WordPress 6.7 as well? Given the timeline, I presume #65700 wasn't part of it? |

I think we should cast to array instead, otherwise, the check won't be applied if there's a single string parent.

Can parent be a string? It doesn't seem so according to the docs. Not knowing all the details of this, I'm a bit reluctant to cast the type.

I doubt it would work with a single string value correctly.
In the block.json schema there is also an array enforced:

After reading a bit. I’m inclined to follow the advice from @youknowriad and cast string values to array to make it backward compatible if there are existing blocks that used the string during the block type’s validation. It happens at the end of this file:

No need to include in 6.7 it seems. |

Is this condition still necessary. I guess right now it's more if ( !! parent )

I'm curious why we'd need both typeof blockType.parent === 'string' || blockType.parent instanceof String.. 🤔

Otherwise, we don't cover all potential issues. Note the issue was that we checked for .length in a type that wasn't an array (didn't have .some). That's the case for both literal & object strings.

It's interesting, but it's possible to pass some constructs like:
I don't think it would ever happen, but the check will cover it.

Potential fix for https://wordpress.org/support/topic/error-after-update-228/
What?
Fixes an error when blocks'
parentproperty is a string.Why?
In the forum, I ran into a report where users have the editor crash when trying to open the inserter. Environment conditions are WordPress 6.6.2 and Gutenberg 15.6. The first error hints at
TypeError: n.parent.some is not a function at ....Investigating a bit, it seems related to #65700 The report is recent (matches the Gutenberg version where that PR was introduced), the users report issues when inserting blocks, and there's no other place in the codebase that uses
parent.some. See conversation.While reproducing the exact user conditions is difficult (e.g.: asking them what 3rd party block libraries do they have, etc.), we can be more explicit about the check.
How?
Update the check for the parent so it verifies it's the type we want it to be: a non-empty array.
Testing Instructions
The best I could come up with is the following:
Using
trunk, the editor would crash. With this PR, it doesn't.Further work
As suggested in https://github.com/WordPress/gutenberg/pull/65700/files#r1806317308 we should look at enforcing the
blockType.parentproperty being an array if that is its only valid value. Given how long we haven't enforced it, doing that now may be side-effects and requires a longer investigation and testing period than this approach — hence why I prioritized preparing this hotfix.
