WSOD editing Jetpack plugin on jetpack.wp.a2z and jetpack.wp-a2z.org. Jetpack 11.3.1 #55

bobbingwide · 2022-09-16T13:07:39Z

Having updated Jetpack to v11.3.1 I wanted to update the list of blocks that Jetpack delivers.
Attempting to edit the oik-plugins jetpack post in both jetpack.wp.a2z and jetpack.wp-a2z.org fails with a white screen of death (WSOD).

Or it could be this message in the Console which occurs when switching oik-blocks/blocklist to showBatch:true and when the prefix is jetpack.

When this error occurs a second and subsequent time there's more in the console log

By fiddling with the oik-block/blocklist settings I was able to get it to display the batch commands for Jetpack 11.3.1
but it crashed again a shortwhile later.

The problem occurs when the Show Block Link toggle is set and the prefix is Jetpack.

I'll try rebuilding oik-batch with the latest wp-scripts and see what happens.
And also try different versions of Jetpack.

See #47

bobbingwide · 2022-09-16T14:57:39Z

On jetpack.wp-a2z.org I got this problem Error: Minified React error #321; visit https://reactjs.org/docs/error-decoder.html?invariant=321 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.
Similar to #55

bobbingwide · 2022-09-16T20:26:39Z

The problem is because the description of the Jetpack Markdown block isn't a string.
the code fails when adding query args.

 url = addQueryArgs( url, { description: block.description });

the block.description for the Markdown block isn't a string. It's a Symbol( react.element )

The source for the Markdown block's description is

description: (
		<Fragment>
			<p>
				{ __(
					'Use regular characters and punctuation to style text, links, and lists.',
					'jetpack'
				) }
			</p>
			<ExternalLink href={ supportLink }>{ __( 'Support reference', 'jetpack' ) }</ExternalLink>
		</Fragment>
	),

See https://github.com/Automattic/jetpack/blob/89a88c1de4a647c90e8ac186a6011e4d9a51caf5/projects/plugins/jetpack/extensions/blocks/markdown/index.js

No. This is a different problem with Jetpack. I should raise an issue.

Line 67 of jetpack_inc\lib\core-api\wpcom-endpoints\subscribers.php is

$subscriber_info  = Jetpack_Subscriptions_Widget::fetch_subscriber_count();

But in my local development environment, which is not connected, the 'subscribers' module isn't loaded.

I had define( 'JETPACK_DEV_DEBUG', true ); in my wp-config.php file.

This may have caused the second part of the expression to be true.

if (
	Jetpack::is_module_active( 'subscriptions' ) ||
	( Constants::is_defined( 'TESTING_IN_JETPACK' ) && Constants::get_constant( 'TESTING_IN_JETPACK' ) )
) {
	wpcom_rest_api_v2_load_plugin( 'WPCOM_REST_API_V2_Endpoint_Subscribers' );
}

OK, so I don't know how to deal with the block.description for Jetpack's Markdown block.

With the current version of the code I'm unable to save the block to display the description list.
It only displays the pre version of the block list.
And I couldn't view the code because that caused the editor to crash.

I'd attempted to deal with the block.description in two ways.

Wrap it in a <Fragment>.

blockDescription = <Fragment>{block.description}</Fragment>;

This worked in the Visual Editor but the block didn't save.
So I've changed the code to use the second alternative.

Check if its a string.

 blockDescription = ( typeof block.description === 'string' ) ? block.description : 'TBC';

This works for all blocks except Jetpack's Markdown. It's a workaround rather than a solution.

bobbingwide · 2022-09-17T15:02:50Z

I think I've found the Gutenberg code that displays the block information I want to save. Its the <BlockCard> component. The README.md for this component suggests that the description prop is expected to be a string.
The code for the BlockCard wraps the description in a <span>.

bobbingwide · 2022-09-18T08:20:53Z

It would appear that the renderToString() function was not suitable.
I tried renderComponent() instead, but it wasn't exported from @wordpress/element.
I then noted that renderToString is actually imported from renderElement, so it looks like it should work.
But the logic in Gutenberg's doesn't appear to cater for $$typeof: Symbol( react.element ).

I thought that maybe I should be using something like

renderToString( <Fragment>{description}</Fragment );

But this results in the WSOD with

react-dom.js:14936 Uncaught Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:

This works for all blocks except Jetpack's Markdown. It's a workaround rather than a solution.

There were a couple of other Jetpack blocks like Markdown.
My most recent attempt at handling the block.description ( see below) worked for these other Jetpack blocks
But it fails for blocks which are variations of template parts, where the description is true. See also blocklist - Don't display the current theme's template variations #54

function BlockDescription( description ) {
    if ( typeof description === 'string' ) {
        return(description);
    } else {
        //console.log( description );
        var descFromFirstPara = 'TBC';
        //descFromFirstPara = renderToString( <Fragment> {description} </Fragment>);
        //console.log( descFromFirstPara);
        var children = description.props.children;
        if ( children[0].type === 'p' ) {
            descFromFirstPara = children[0].props.children;
        }
        return( descFromFirstPara );
    }
}

The problem with saving the description field also applies to the oik/block-info block
where the selected block is jetpack/payment-buttons.

#55

bobbingwide · 2022-09-22T11:38:09Z

Looks like I wasn't the only person affected by different routine's misuse of the description field. Gutenberg 14.1.1 was released to fix a similar problem with Search. See WordPress/gutenberg#44233

IMO the documentation for registerBlockType() should be updated. See https://developer.wordpress.org/block-editor/reference-guides/block-api/block-registration/
