During taxi out for takeoff at ZZZ we received an ACARS message stating that 'the load close out was invalid' and that we must wait for a valid load close. I got distracted and forgot about getting a valid load closeout and we departed and flew uneventfully to ZZZ1. The Captain and I had had a successful trip. We worked well together. This was our last leg home on our last day. We had confidence in each other and perhaps that led to complacency. We had just been delayed at the gate for a COVID concern. I think we had a runway change and I got distracted.Perhaps; in the future; I will Scribble 'void' over the invalid load close out so that we do not mistakenly use it.
Air carrier First Officer reported becoming distracted and not getting a valid load close out.
