GOOGLE FORM to OPENAI (synthesis) to EMAIL?


I’ve tried to create a flow for … quite some time to no avail as I am just beginning on this n8n…

Once a month I want to :

Read a Google Form data Sheet answers
Send it to OPENAI to make a synthesis/report
Send it by EMAIL


Schedule Trigger “Once a month” : OK
Google Sheet “Read” : OK
Summarization Chain : NOK

Error displayed

“No node connected to required input model”
“No node connected to required document”

Information on your n8n setup

Is it possible ?

Thanks in advance,


It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hey @Fei,

The error you are seeing is because you have not added a model or a document to the summarisation node, although I don’t think this is the best node to use as the data is not from a document.

Instead you could try the OpenAI node and create a prompt including your data to do the work.
