Generating Invoice in Airtable

i am trying to create an invoice with google docs template and airtable but i can’t update my invoice url in airtable after the invoice has updated. i keep getting an error that the fields need to be an array
below is an image of my workflow

Any help please?

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:

Could you provide the error you are getting? And also which nodes the error is coming in.

Also you need to check the data structure from the previous node and see if they match. Note there is a difference between a sting and array data and if this is not correct n8n will throw in an error.

Let me know if this helps

This doesnt provide enough enough to recreate the workflow to detect the error. But if the other nodes are sending the correct data, then the code node it what has an issue. What you can do is check the n8n data structures to use on the code then then map the final airtable node
