Wixdata.query result is different at preview and live mode

My code is:

wixData.query("SampleDB").
                        eq(menuName, category).
                        find().then((results) => {
                            console.log(results.items);
                    })

Preview mode result is:

And live mode result is:

Can you explain why can’t I check my data at live site?
