Hey @erichuang
Hmm this node should use the same credential and database as set in step 3. You may need to manually update these by toggling the dropdowns in this notion node and others after it.
Hey @Jude_SV welcome to the community!
Good catch, I think this might be a bug - the follow-up questions were previously generated by the “DeepResearch Learnings” agent in step 9 but were removed (not sure what happened…). I’ll fix it in the next update.

Thanks Jim! Just an additional question, since that’s showing as undefined does that mean that the loop isn’t able to go through and answer all the follow up questions so when the loop if triggered the condition immediately becomes true? So it only passes the loop once? Sorry, still very new to this and I’m currently studying your workflow.
Thanks Jim, now the issue is solved, I guess it might be due to my question given to the agent. I found that if the questions are too short, such as “AI” and then in the following question I say “no other questions”, then the loop has problem haha.
Again thanks for sharing this and inspire me for my biology study.
I get this error with the workflow, the subworkflow just sits on waiting it seems - any ideas how to solve it or debug? Really keen to test this, appreciate you putting it together!
Just to answer this for any future readers - I used a different browser (chrome) and it progressed past this point 
Hey Jude and Jim, not sure if you solve this or not but I think someone else may encounter this. For me, this was one small but incrementally reduced the performance of the research.
It turned out that in the latest version of this amazing workflow, these 2 nodes was a bit different from the old version in “n8n_deepresearch_community_share.json - Google Drive” (link in this post as well)
I replace it and it works perfect now !! Thanks Jim for this workflow
