use optional chaining on your data array

[Ras443]

Can you eloborate that?

Rather than data.filter, do data?.filter. Sometimes your internet might be slow, so data which you're fetching might not arrive when immediately. So when you run data.filter, since data would be currently empty, you can't filter an empty or nonexistent array, so it would throw an error. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining
