How to retrieve block data?

[mustson]

// Retrieve block details once and use throughout
const block = this.api.blocks.getBlockByIndex(blockIndex);

        console.log('Block data:', block.data, 'Block index:', blockIndex);
        if (!block || !block.id) {
            throw new Error('No valid ID for the current block.');
        }

        const originalText = block.data?.text; // Using optional chaining for safety
        console.log(block);
        
        Block data is undefined, how do I retrieve the contents of a block, such as the text of a paragraph of heading? Or a list content?

Data is undefined at constructor,

export default class MyBlockTune { static get isTune() { return true; } constructor({ api, data, config, block }) { this.api = api; this.data = data; this.config = config; this.block = block; console.log('Constructor called'); console.log('Constructor data:', data); console.log('Constructor block:', block); // Set up a listener for when the block data might change }

why?!

here is the initiation:

`const editor = new EditorJS({
                holder: 'editorjs',
                data: {
                    blocks: articleBlocks,
                },
                tools: {
                    myBlockTune: {
                        class: MyBlockTune,
                        config: {
                            // Important: Does your tune need specific data to work?
                            // Example
                        },
                    },
                    header: {
                        class: Header,
                    },
                    paragraph: {
                        class: Paragraph,
                        tunes: ['myBlockTune'], // Add the tune to the header tool
                    },
                    list: List,
                    image: Image,

                    // Add more tools as needed
                },
            });`
