Describe the problem/error/question
I am doing my first workflow following a tutorial. Everything is fine until I am adding a Pinecone sub node. In the video, I should be entering a Name. However, the UI doesn’t give me that option. I looked at it many times, but it looks like there’s nothing I can do.
What is the error message (if any)?
Error in sub-node ‘Pinecone Vector Store1‘
Invalid input for ‘Name’ [item 0]
Open node
