I am running this workflow where I am scrapping the reddit and certain sub reddits and combining them to get AI summary in a doc. but ChatGPT is taking each post as one not combining them and I am having error in this node which combines all the lists.

Can Anybody help me solve this. This is a client project and I need help. Thankyou!
