Rapid Product Development with n8n

Questions

I am having trouble with some of the examples in the book and thus I have questions about them. Do any of the authors answer questions in this forum?

1.) on page 130 I can’t get the IF node to return results to the “TRUE” side.
Here is my code:

2.) on page 142 I can’t get WorkFlow 1 to run WorkFlow 2
Here is the code:

Thank you for your help.

What is the error message (if any)?

Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

I’m not familiar with the book so can’t comment on the first question, but for the second question you need to set the numeric ID of the subworkflow you’re calling in the ‘execute workflow’ node. You can find this either in the URL or the workflow settings:

Yes, thank you. I found the numeric ID of the subworkflow and input it in the database setting where it asks for the numeric ID, but now I get the following error: " ERROR: Your request is invalid or could not be processed by the service

Unknown field name: “created_at”

Do I need a set node before the Execute Workflow node?
