Error in running playground demo

The debugging info:
TreeView.svelte:184 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length')

demo from playground.
Code from 20240925
Reproduction:
1 run the playground demo
2 goto setting button
3 turn on debug view bar
4 turn off debug view bar
then the error found in the console.

How to resolve:
function generateContent(
editor: LexicalEditor,
commandsLog: ReadonlyArray<
{index: number} & LexicalCommand & {payload: unknown}

,
exportDOM: boolean,
): string {
// 在这里实现你的生成内容逻辑
// 假设这里的代码可能会导致 TypeError
}

// 在调用 generateContent 之前进行检查
if (editor && commandsLog !== undefined) { <<---------should add undefined checking ?
if (Array.isArray(commandsLog) && commandsLog.length > 0) {
const content = generateContent(editor, commandsLog, exportDOM);
// 使用生成的内容
} else {
console.error('commandsLog is not an array or is empty.');
}
} else {
console.error('editor or commandsLog is undefined.');
}
