Children of Frame returned an empty array, but visible in console

(post deleted by author)

Answering my findAll part of the question, turns out I should put

const cell = figma.createFrame();
cell.name = 'Cell';

before await figma.loadFontAsync(text.fontName); otherwise the cell name will still be ‘Frame’. So the search works, I think the forEach also has something to do with Async createText(), still not sure why.

answer my own question again, double forEach works 🤔 I don’t know why it’s not working eariler.

const allSelect = () =>{
    const selection = [];
    const mainFrame = figma.currentPage.findAll((node) => node.name === 'Mainframe-'+ id);  
    mainFrame[0].children.forEach ((node) => {
        node.children.forEach((child) => {
            if (child.name = 'Cell') {
                selection.push(child);
            }
        }
        );
    } );
    return selection;
}
