Adapting to variable size inputs with GCal

Describe the issue/error/question

I’m trying to connect GMail with GCal such that the sender / all CC’d get added to a cal invite. However, because the CC’d is a variable size (0, 1, many), it seems that sometimes I run into errors (field doesn’t exist, Gcal can’t handle an array instead of string).

Do you have recommendations on how to execute the workflow?

What is the error message (if any)?

Please share the workflow

(Select the nodes and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow respectively)

Share the output returned by the last node

Information on your n8n setup

  • n8n version:
  • Database you’re using (default: SQLite):
  • Running n8n with the execution process [own(default), main]:
  • Running n8n via [Docker, npm,, desktop app]:

Hi @christopherkang, welcome to the community!

I am sorry to hear you’re having trouble. Perhaps you can share your workflow as well as some example data causing the trouble so we can get an idea of what exactly isn’t working for you?
