Dynamically grab data for data driven tests in CodeceptJs

Question

I want to run data driven tests in CodeceptJs, but I don't have a fixed data set. I have to grab the data before the test. I am on a webpage, that has a table and inside that table I find my data. I want to grab it and then run the test with whatever data I got. I tried something like this, but it didn't work:

let data = new DataTable(['id']);

BeforeSuite(async ({I}) => {    
    I.amOnPage('my_portalpage');
    const ids = await I.grabAttributeFromAll('.data', 'data-id');
    ids.map((id) => {
        data.add([id]);
    })
});

Data(data).Scenario('Run tests using the data', async ({ I, current }) => {
    // do stuff for current.id
})

The result is that the scenarios just don't run. I tried to grab the data inside a scenario, with the same result. I guess the data has to be fully defined right at the beginning, but how can I do that? There is no API I can use to get the data, I have to go to the page and grab it.

Thanks in advance!
