Suggestion for: (2677712) Overview

Documentation location/URL

web/core/modules/big_pipe/js/big_pipe.js

Problem/Motivation

TypeError: Cannot read properties of null (reading 'nodeType')

this is in code
/**
* Checks if node is valid big pipe replacement.
*/
function checkMutation(node) {
return Boolean(
node.nodeType === Node.ELEMENT_NODE &&
node.nodeName === 'SCRIPT' &&
node.dataset &&
node.dataset.bigPipeReplacementForPlaceholderWithId &&
typeof drupalSettings.bigPipePlaceholderIds[
node.dataset.bigPipeReplacementForPlaceholderWithId
] !== 'undefined',
);
}

Proposed resolution

/**
* Checks if node is valid big pipe replacement fix.
*/
function checkMutation(node) {
return Boolean(
node &&
node.nodeType === Node.ELEMENT_NODE &&
node.nodeName === 'SCRIPT' &&
node.dataset &&
node.dataset.bigPipeReplacementForPlaceholderWithId &&
typeof drupalSettings.bigPipePlaceholderIds[
node.dataset.bigPipeReplacementForPlaceholderWithId
] !== 'undefined'
);
}

Remaining tasks

only need to change this to fix the error in js
