Bug: Notion rich_text[] max length is 100, markdownToBlocks() can create more than the limit

[roberttolton]

Hi, thanks for this package!

I noted in the documentation that it should automatically try and spread data that would be too long into multiple blocks, however after using markdownToBlocks() with some data that contained many lines and line breaks, the result was a paragraph block with a rich_text array that had over 100 items, which is over Notion's API limit for rich_text items.

When reading the docs, I thought it might try and spread the excess rich_text items into other blocks, but looking at the source code it will either truncate the array or leave it as it is - I think we should create X-amount of blocks until all excess rich_text items can fit?

Solution in my code for now:

// some code redacted
// import LIMITS
// chunk() is like a lodash chunk function

const blocks = markdownToBlocks(markdown)

blocks.forEach((block, blockIndex) => {

    if (
        block.type === 'paragraph' &&
        block.paragraph.rich_text.length > LIMITS.RICH_TEXT_ARRAYS
    ) {

        const newParagraphBlocks = []
        const richTextChunks = chunk(block.paragraph.rich_text, 100)

        richTextChunks.forEach(chunk => {
            newParagraphBlocks.push(paragraph(chunk))
        })

        blocks.splice(blockIndex, 1, ...newParagraphBlocks)

    }

})

I tried your code with no success.

Did they update the requirements ? https://developers.notion.com/reference/request-limits

It looks like any array of more than 100 blocks is not allowed now.

Also having this issue.

Tried to upload something and got the error Error adding block: 400 - {"object":"error","status":400,"code":"validation_error","message":"body failed validation: body.children.length should be ≤ 100, instead was 139.","request_id":""}
